MAX4053CSE+中文资料
General Description
The MAX4051/MAX4052/MAX4053 and
MAX4051A/MAX4052A/MAX4053A are low-voltage, CMOS
analog ICs configured as an 8-channel multiplexer
(MAX4051/A),two 4-channel multiplexers (MAX4052/A), and
three sin-gle-pole/double-throw (SPDT) switches
(MAX4053/A).The A-suffix parts are fully characterized for on-resistance match, on-resistance flatness, and low leakage.
These CMOS devices can operate continuously with dual
power supplies ranging from ±2.7V to ±8V or a single supply
between +2.7V and +16V. Each switch can handle rail-to-rail
analog signals. The off-leakage current is only 0.1nA at +25°C or
5nA at +85°C (MAX4051A/MAX4052A/MAX4053A).
All digital inputs have 0.8V to 2.4V logic thresholds,ensuring
TTL/CMOS-logic compatibility when using ±5V or a single +5V
supply.

max3485eesa + T概述
Max3485eesa + T是3.3V电源±15kV ESD保护，真正的RS485
/ RS422收发器，采用8引脚nsoic封装。该低功耗收发器包含一个驱动器和一个接收器。max3485e传输速率高达15Mbps。它具有增强的静电保护。所有发送器输出和接收器输入均具有±15kV保护，并通过IEC 1000-4-2气隙放电；±8Kv保护是通过IEC 1000-4-2接触放电，±15kV保护是通过人体模型。驱动器受到短路电流的限制，并通过将驱动器输出置于高阻抗状态的热关断电路来防止过多的功耗。接收器输入具有故障安全功能，如果两个输入均打开，则提供逻辑高电平输出。Max3485e适用于EMI敏感应用，集成服务，数字网络和数据包交换

Max3483，max3485，max3486，max3488，max3490和max3491是用于RS-485和RS-422通信的3.3V低功耗收发器，每个收发器都有一个驱动器和一个接收器。Max3483和max3488具有有限速率驱动器，可以降低EMI并减少由于端子匹配电缆不合适而引起的反射，从而实现高达250kbps的无错误数据传输。由于其有限的摆幅速率，Max3486可以实现最大2.5mbps 的传输速率。Max3485，max3490和max3491可以实现高达10Mbps的传输速率。
驱动器具有短路电流限制，并且可以通过热关断电路将驱动器的输出设置为高阻状态，以防止过多的功率损耗。接收器输入具有故障安全功能，以确保在输入断开时输出逻辑高电平。
General DescriptionThe MAX200–MAX211/MAX213 transceivers aredesigned for RS-232 and V.28 communication inter-faces where ±12V supplies are not available. On-boardcharge pumps convert the +5V input to the ±10V need-ed for RS-232 output levels. The MAX201 and MAX209operate from +5V and +12V, and contain a +12V to -12V charge-pump voltage converter.The MAX200–MAX211/MAX213 drivers and receiversmeet all EIA/TIA-232E and CCITT V.28 specifications ata data rate of 20kbps. The drivers maintain the ±5VEIA/TIA-232E output signal levels at data rates inexcess of 120kbps when loaded in accordance with theEIA/TIA-232E specification.The 5µW shutdown mode of the MAX200, MAX205,MAX206, and MAX211 conserves energy in battery-powered systems. The MAX213 has an active-low shut-down and an active-high receiver enable control. Tworeceivers of the MAX213 are active, allowing ring indica-tor (RI) to be monitored easily using only 75µW power.The MAX211 and MAX213 are available in a 28-pinwide small-outline (SO) package and a 28-pin shrinksmall-outline (SSOP) package, which occupies only40% of the area of the SO. The MAX207 is now avail-able in a 24-pin SO package and a 24-pin SSOP. TheMAX203 and MAX205 use no external components,and are recommended for applications with limited circuit board space.ApplicationsComputersLaptops, Palmtops, NotebooksBattery-Powered Equipment

Maxim Integrated Products1General Description
The MAX202E–MAX213E, MAX232E/MAX241E linedrivers/receivers are designed for RS-232 and V.28communications in harsh environments. Each transmitteroutput and receiver input is protected against ±15kVelectrostatic discharge (ESD) shocks, without latchup.The various combinations of features are outlined in theSelector Guide.The drivers and receivers for all tendevices meet all EIA/TIA-232E and CCITT V.28specifications at data rates up to 120kbps, when loadedin accordance with the EIA/TIA-232E specification.
The MAX211E/MAX213E/MAX241E are available in 28-pin SO packages, as well as a 28-pin SSOP that uses60% less board space. The MAX202E/MAX232E comein 16-pin TSSOP, narrow SO, wide SO, and DIPpackages. The MAX203E comes in a 20-pin DIP/SOpackage, and needs no external charge-pumpcapacitors. The MAX205E comes in a 24-pin wide DIPpackage, and also eliminates external charge-pumpcapacitors. The MAX206E/MAX207E/MAX208E come in24-pin SO, SSOP, and narrow DIP packages. TheMAX232E/MAX241E operate with four 1µF capacitors,while the MAX202E/MAX206E/MAX207E/MAX208E/MAX211E/MAX213E operate with four 0.1µF capacitors,further reducing cost and board space.
