The output of the detector is an open collector Schottky clamped transistor. Internal shields provide a guaranteed common mode transient immunityspecification of 1000 V/µs. For Isolation Voltage applications requiring up to 2500 Vdc, the HCPL-5650 family is also available. Package styles for these parts are 8 and 16 pin DIP through hole (case outlines P andE respectively), and 16 pin surface mount DIP flat pack(case outline F), leadless ceramic chip carrier (case outline 2).Devices may be purchased with a variety of lead bend and plating options. See Selection Guide Table for details. Standard Microcircuit Drawing (SMD)parts are available for each package and lead style.Because the same electrical die (emitters and detectors) are used for each channel of each device listed in this data sheet, absolute maximum ratings, recommended operating conditions, electrical specifications, and performance characteristics shown in the figures are identical for all parts.Occasional exceptions exist due to package variations and limitations,and are as noted. Additionally, the same package assembly processes and materials are used in all devices. These similarities give justification for the use of data obtained from one part torepresent other parts’ performance for reliability and certain limited radiation test results.Outline Drawings16 Pin DIP Through Hole, 2 ChannelsFunctional DiagramsNote: All DIP and flat pack devices have common V CC and ground.

CM L is the maximum rate of rise of the common mode voltage that can be sustained with the output voltage in the logic low state(V O < 0.8 V). CM H is the maximum rate of fall of the common mode voltage that can be sustained with the output voltage in the logic high state (V O > 2.0 V).8. This is a momentary withstand test, not an operating condition.9. It is essential that a bypass capacitor (0.01 to 0.1 µF, ceramic) be connected from V CC to ground. Total lead length between bothends of this external capacitor and the isolator connections should not exceed 20 mm.10. No external pull up is required for a high logic state on the enable input.11.

54/74374八上升沿D触发器(3S,时钟输入有回环特性)简要说明:374为具有三态输出的八D边沿触发器,共有54/74S374和54/74LS374两种线路结构型式，其主要电器特性的典型值如下(不同厂家具体值有差别):型号f m P D54S374/74S374 100MHz 450mW54LS374/74LS374 50MHz 135mW374的输出端O0~O7可直接与总线相连。

当三态允许控制端OE为低电平时，O0~O7为正常逻辑状态，可用来驱动负载或总线。

当OE为高电平时，O0~O7呈高阻态，即不驱动总线，也不为总线的负载，但锁存器内部的逻辑操作不受影响。

当时钟端CP脉冲上升沿的作用下，O随数据D而变。

由于CP端施密特触发器的输入滞后作用，使交流和直流噪声抗扰度被改善400mV。

General DescriptionThe MAX6314 low-power CMOS microprocessor (µP)supervisory circuit is designed to monitor power supplies in µP and digital systems. The MAX6314’s RESET output is bidirectional, allowing it to be directly connected to µPs with bidirectional reset inputs, such as the 68HC11. It provides excellent circuit reliability and low cost by eliminating external components and adjustments. The MAX6314 also provides a debounced manual reset input.This device performs a single function: it asserts a reset signal whenever the V CC supply voltage falls below a preset threshold or whenever manual reset is asserted.Reset remains asserted for an internally programmed interval (reset timeout period) after V CC has risen above the reset threshold or manual reset is deasserted.The MAX6314 comes with factory-trimmed reset threshold voltages in 100mV increments from 2.5V to 5V. Preset timeout periods of 1ms, 20ms, 140ms,and 1120ms (minimum) are also available.

Connect to V CC if not used.MR 3PIN Active-Low Complementary Output. In addition to the normal n-channel pulldown, RESET has a p-channel pullup transistor in parallel with a 4.7k Ωresistor to facilitate connection to µPs with bidirectional resets. See the Reset Output section.RESET2GroundGND 1FUNCTIONNAMEMAX631468HC11/Bidirectional-CompatibleµP Reset Circuit_______________________________________________________________________________________5Detailed DescriptionThe MAX6314 has a reset output consisting of a 4.7k Ωpull-up resistor in parallel with a P-channel transistor and an N-channel pull down (Figure 1), allowing this IC to directly interface with microprocessors (µPs) that have bidirectional reset pins (see the Reset Output section).Reset OutputA µP’s reset input starts the µP in a known state. The MAX6314 asserts reset to prevent code-execution errors during power-up, power-down, or brownout conditions. RESET is guaranteed to be a logic low for V CC > 1V (see the Electrical Characteristics table).Once V CC exceeds the reset threshold, the internal timer keeps reset asserted for the reset timeout period (t RP ); after this interval RESET goes high. If a brownout condition occurs (monitored voltage dips below its pro-grammed reset threshold), RESET goes low. Any time V CC dips below the reset threshold, the internal timer resets to zero and RESET goes low. The internal timer starts when V CC returns above the reset threshold, and RESET remains low for the reset timeout period.The MAX6314’s RESET output is designed to interface with µPs that have bidirectional reset pins, such as the Motorola 68HC11. Like an open-drain output, the MAX6314 allows the µP or other devices to pull RESET low and assert a reset condition. However, unlike a standard open-drain output, it includes the commonly specified 4.7k Ωpullup resistor with a P-channel active pullup in parallel.This configuration allows the MAX6314 to solve a prob-lem associated with µPs that have bidirectional reset pins in systems where several devices connect to RESET . These µPs can often determine if a reset was asserted by an external device (i.e., the supervisor IC)or by the µP itself (due to a watchdog fault, clock error,or other source), and then jump to a vector appropriate for the source of the reset. However, if the µP does assert reset, it does not retain the information, but must determine the cause after the reset has occurred.The following procedure describes how this is done with the Motorola 68HC11. In all cases of reset, the µP pulls RESET low for about four E-clock cycles. It then releases RESET , waits for two E-clock cycles, then checks RESET ’s state. If RESET is still low, the µP con-cludes that the source of the reset was external and,when RESET eventually reaches the high state, jumps to the normal reset vector. In this case, stored state information is erased and processing begins fromscratch. If, on the other hand, RESET is high after the two E-clock cycle delay, the processor knows that it caused the reset itself and can jump to a different vec-tor and use stored state information to determine what caused the reset.The problem occurs with faster µPs; two E-clock cycles is only 500ns at 4MHz. When there are several devices on the reset line, the input capacitance and stray capacitance can prevent RESET from reaching the logic-high state (0.8 x V CC ) in the allowed time if only a passive pullup resistor is used. In this case, all resets will be interpreted as external. The µP is guaranteed to sink only 1.6mA, so the rise time cannot be much reduced by decreasing the recommended 4.7k Ωpullup resistance.The MAX6314 solves this problem by including a pullup transistor in parallel with the recommended 4.7k Ωresis-tor (Figure 1). The pullup resistor holds the output high until RESET is forced low by the µP reset I/O, or by the MAX6314 itself. Once RESET goes below 0.5V, a com-parator sets the transition edge flip-flop, indicating that the next transition for RESET will be low to high. As soon as RESET is released, the 4.7k Ωresistor pulls RESET up toward V CC . When RESET rises above 0.5V,the active p-channel pullup turns on for the 2µs duration of the one-shot. The parallel combination of the 4.7k Ωpullup and the p-channel transistor on-resistance quickly charges stray capacitance on the reset line, allowing RESET to transition low to high with-in the required two E-clock period, even with several devices on the reset line (Figure 2). Once the one-shot times out, the p-channel transistor turns off. This process occurs regardless of whether the reset was caused by V CC dipping below the reset threshold, MR being asserted, or the µP or other device asserting RESET . Because the MAX6314 includes the standard 4.7k Ωpullup resistor, no external pullup resistor is required. To minimize current consumption, the internal pullup resistor is disconnected whenever the MAX6314asserts RESET .Manual Reset InputMany µP-based products require manual reset capabil-ity, allowing the operator, a test technician, or external logic circuitry to initiate a reset. A logic low on MR asserts reset. Reset remains asserted while MR is low,and for the reset active timeout period after MR returns high. To minimize current consumption, the internal 4.7k Ωpullup resistor on RESET is disconnected whenever RESET is asserted.M A X 631468HC11/Bidirectional-Compatible µP Reset Circuit 6_______________________________________________________________________________________MR has an internal 63k Ωpullup resistor, so it can be left open if not used. Connect a normally open momen-tary switch from MR to GND to create a manual reset function; external debounce circuitry is not required. If MR is driven from long cables or if the device is used in a noisy environment, connecting a 0.1µF capacitor from MR to ground provides additional noise immunity.__________Applications InformationNegative-Going V CC TransientsIn addition to issuing a reset to the µP during power-up,power-down, and brownout conditions, these devices are relatively immune to short-duration negative-going transients (glitches). The T ypical Operating Character-istics show the Maximum Transient Duration vs. Reset Threshold Overdrive, for which reset pulses are not generated. The graph was produced using negative-going pulses, starting at V RST max and ending below the programmed reset threshold by the magnitude indicated (reset threshold overdrive). The graph shows the maximum pulse width that a negative-going V CC transient may typically have without causing a reset pulse to be issued. As the amplitude of the transient increases (i.e., goes farther below the reset threshold),the maximum allowable pulse width decreases. A 0.1µF bypass capacitor mounted close to V CC provides addi-tional transient immunity.Ensuring a Valid RESET OutputDown to V CC = 0VWhen V CC falls below 1V, RESET no longer sinks current—it becomes an open circuit. Therefore, high-impedance CMOS-logic inputs connected to RESET can drift to undetermined voltages. This presents no problem in most applications, since most µP and other circuitry is inoperative with V CC below 1V. However, in applications where RESET must be valid down to V CC = 0V, adding a pull-down resistor to RESET will cause any stray leakage currents to flow to ground,holding RESET low (Figure 3). R1’s value is not critical;100k Ωis large enough not to load RESET and small enough to pull RESET to ground.Figure 2. MAX6314 Supports Additional Devices on the Reset BusFigure 3.
