当有电话呼入时，电话线上传输的25HZ、90V 的交流振铃信号由C1、C2隔离直流后由整流桥整流，整流后的直流电压值较高，经光电隔离器U1后输出TTL脉冲信号，该脉冲经74LS123整形成大方波信号，该方波信号送至单片机的P3.5引脚进行计数，当计数值达到预设值时，单片机P1.0引脚输出高电平，三极管Q1导通则继电器K1动作，将负载电阻R5（330Ω）接入电路实现模拟摘机。

这里所说的模拟摘机是指将R5接入电路后，电话线上就会出现大于10mA的电流，交换中心检测到这一电流后就不再输出振铃信号而是转为接通电话。

人们手动摘机接通电话时的工作过程与此一致，因此称为模拟摘机。

如果振铃信号没有达到预设值就消失，则单片机的计数值清零，控制器不动作。

© 2000 Fairchild Semiconductor Corporation DS006386August 1986Revised April 2000DM74LS123 Dual Retriggerable One-Shot with Clear and Complementary OutputsDM74LS123Dual Retriggerable One-Shotwith Clear and Complementary OutputsGeneral DescriptionThe DM74LS123 is a dual retriggerable monostable multi-vibrator capable of generating output pulses from a few nano-seconds to extremely long duration up to 100% duty cycle. Each device has three inputs permitting the choice of either leading edge or trailing edge triggering. Pin (A) is an active-LOW transition trigger input and pin (B) is an active-HIGH transition trigger input. The clear (CLR) input termi-nates the output pulse at a predetermined time indepen-dent of the timing components. The clear input also serves as a trigger input when it is pulsed with a low level pulse transition ( ). To obtain the best trouble free operation from this device please read the operating rules as well as the Fairchild Semiconductor one-shot application notes carefully and observe recommendations.Featuress DC triggered from active-HIGH transition or active-LOW transition inputs s Retriggerable to 100% duty cycles Compensated for V CC and temperature variations s Triggerable from CLEAR input s DTL, TTL compatible s Input clamp diodesOrdering Code:Devices also available in T ape and Reel.

Once trig-gered, the basic pulse width may be extended by retrigger-ing the gated active-LOW transition or active-HIGH transition inputs or be reduced by use of the active-LOW orCLEAR input. Retriggering to 100% duty cycle is possible by application of an input pulse train whose cycle time is shorter than the output cycle time such that a continuous “HIGH ” logic state is maintained at the “Q ” output.Operating Rules1.An external resistor (R X ) and an external capacitor (C X )are required for proper operation. The value of C X may vary from 0 to any necessary value. For small time con-stants high-grade mica, glass, polypropylene, polycar-bonate, or polystyrene material capacitors may be used. For large time constants use tantalum or special aluminum capacitors. If the timing capacitors have leakages approaching 100 nA or if stray capacitance from either terminal to ground is greater than 50 pF the timing equations may not represent the pulse width the device generates.2.When an electrolytic capacitor is used for C X a switch-ing diode is often required for standard TTL one-shots to prevent high inverse leakage current. This switching diode is not needed for the DM74LS123 one-shot and should not be used. In general the use of the switching diode is not recommended with retriggerable operation.Furthermore, if a polarized timing capacitor is used on the DM74LS123 the negative terminal of the capacitor should be connected to the “C EXT ” pin of the device (Figure 1).FIGURE 1.3.For C X >> 1000 pF the output pulse width (t W ) isdefined as follows:t W = KR X C X where [R X is in k Ω][C X is in pF][t W is in ns]K ≈ 0.374.The multiplicative factor K is plotted as a function of C Xbelow for design considerations:FIGURE 2.5.For C X < 1000 pF see Figure 3 for t W vs. C X familycurves with R X as a parameter:FIGURE 3.6.To obtain variable pulse widths by remote trimming, thefollowing circuit is recommended:FIGURE 4.“R remote ” should be as close to the device pin as possible.7.The retriggerable pulse width is calculated as shownbelow:T = t W + t PLH = K × R X × C X + t PLHThe retriggered pulse width is equal to the pulse width plus a delay time period (Figure 5).FIGURE 5.DM74LS123Operating Rules (Continued)8.Output pulse width variation versus V CC and tempera-tures: Figure 6 depicts the relationship between pulse width variation versus V CC , and Figure 7 depicts pulse width variation versus temperatures.FIGURE 6.FIGURE 7.9.Under any operating condition C X and R X must be keptas close to the one-shot device pins as possible to min-imize stray capacitance, to reduce noise pick-up, and to reduce I-R and Ldi/dt voltage developed along their connecting paths. If the lead length from C X to pins (6)and (7) or pins (14) and (15) is greater than 3 cm, for example, the output pulse width might be quite different from values predicted from the appropriate equations.A non-inductive and low capacitive path is necessary to ensure complete discharge of C X in each cycle of its operation so that the output pulse width will be accu-rate.10.The C EXT pins of this device are internally connected tothe internal ground. For optimum system performance they should be hard wired to the system ’s return ground plane.11.V CC and ground wiring should conform to good high-frequency standards and practices so that switching transients on the V CC and ground return leads do not cause interaction between one-shots. A 0.01 µF to 0.10µF bypass capacitor (disk ceramic or monolithic type)from V CC to ground is necessary on each device. Fur-thermore, the bypass capacitor should be located as close to the V CC -pin as space permits.Note: For further detailed device characteristics and output per-formance please refer to the Fairchild Semiconductor one-shot application note AN-372. 4D M 74L S 123Absolute Maximum Ratings (Note 1)Note 1: The “Absolute Maximum Ratings ” are those values beyond which the safety of the device cannot be guaranteed.

RETRIGGERABLE MONOSTABLE MULTIVIBRATORSThese dc triggered multivibrators feature pulse width control by three meth-ods. The basic pulse width is programmed by selection of external resistance and capacitance values. The LS122 has an internal timing resistor that allows the circuits to be used with only an external capacitor. Once triggered, the ba-sic pulse width may be extended by retriggering the gated low-level-active (A)or high-level-active (B) inputs, or be reduced by use of the overriding clear.•Overriding Clear Terminates Output Pulse•Compensated for V CC and T emperature Variations•DC Triggered from Active-High or Active-Low Gated Logic Inputs •Retriggerable for Very Long Output Pulses, up to 100% Duty Cycle •Internal Timing Resistors on LS122SN54/74LS122 (TOP VIEW)(SEE NOTES 1 THRU 4)SN54/74LS123 (TOP VIEW)(SEE NOTES 1 THRU 4)NOTES:1.An external timing capacitor may be connected between C ext and R ext /C ext (positive).2.To use the internal timing resistor of the LS122, connect R int to V CC .3.For improved pulse width accuracy connect an external resistor between R ext /C ext and V CC with R int open-circuited.4.To obtain variable pulse widths, connect an external variable resistance between R int /C ext and V CC .R ext/CR ext/C ext 11ĂRext/2CLRC extNC Ċ NO INTERNAL CONNECTION.。
