M74HC221功能描述
3) A是低电平且B是高电平，同时C1有一个上升沿时.
当多谐振荡器触发之后，比较器C1和C2 开始运行，同时Qn被打开. 然后Cx通过Qn放电. 外接R/C点的电压下降。当达到VREFL时，比较器C1的输出变成低电平。 这转而复位触发器，同时Qn被关闭。此时，C1停止运行，C2接替运行。外接R/C的电压开始以一个由外部元件Rx, Cx决定的时间常数上升。
功能描述
一、待机状态
在待机状态，外部电容完全充电至VCC。 因此, 触发之前, 晶体管 Qp 和 Qn (连接到 Rx/Cx 点) 都是关闭状态. 控制时间的两个比较器和两个参考电压源停止动作。总的供电电流只有漏电流。
二、触发动作
当以下情况时发生触发 :
1) A是低电平且B有一个下降沿时 ;
tW(OUT) = 0.70 Cx/Rx (HC221)
tW(OUT) =Cx/Rx (HC221A)
三、复位动作 Байду номын сангаас
CL正常情况下是高电平，如果CL出现低电平，触发信号无效。因为Q端输出呈低电平且触发信号控制触发器复位。
并且，晶体管Op被打开，Cx被快速充电至VCC。这意味着如果CL输入降为低电平，IC在工作和非工作状态都变为等待状态。
由于触发器和门限，经过内部延时后触发多谐振荡器造成Q升到高电平。Q保持高电平直到外部R/C的电压再次升高到VREFH。这时，C2的输出降为低电平且O变为低电平。C2停止运行。这意味着在触发之后，当外接R/C电压返回到VREFH时，多谐振荡器已经返回到单稳状态。当Rx /Cx足够大且电容的放电时间和IC内部延时可以被忽略时，输出脉宽tw (out)为：

June 1997Revised April 199974VHCT540A Octal Buffer/Line Driver with 3-STATE Outputs © 1999 Fairchild Semiconductor Corporation DS500012.prf 74VHCT540AOctal Buffer/Line Driver with 3-STATE OutputsGeneral DescriptionThe VHCT540A is an advanced high-speed CMOS devicefabricated with silicon gate CMOS technology. It achievesthe high-speed operation similar to equivalent BipolarSchottky TTL while maintaining the CMOS low power dissi-pation.The VHCT540A is an octal buffer/line driver designed to beemployed as memory and address drivers, clock driversand bus oriented transmitter/receivers.This device is similar in function to the VHCT240A whileproviding flow-through architecture (inputs on opposite sidefrom outputs). This pinout arrangement makes this deviceespecially useful as an output port for microprocessors,allowing ease of layout and greater PC board density.Protection circuits ensure that 0V to 7V can be applied tothe input and output (Note 1) pins without regard to thesupply voltage. This device can be used to interface 3V to5V systems and two supply systems such as batterybackup. This circuit prevents device destruction due to mis-matched supply and input voltages.Note 1: Outputs in OFF-STATEFeaturess High Speed:t PD= 5.4 ns (typ) at V CC= 5Vs Low Power Dissipation:I CC= 4 µA (max) at T A= 25°Cs Power down protection is provided on all inputs andoutputss Pin and function compatible with 74HCT540Ordering Code:Surface mount packages are also available on Tape and Reel.

These inputs are valid for slow rising/falling signals, (tr=tf=l sec).The device may also be triggered by using the CLR input (positive-edge) because of the Schmitt-trigger input; after triggering the output maintains the MONOSTABLE state for the time period determined by the external resistor Rx and capacitor Cx. When Cx > 10nF and Rx > 10K Ω,the output pulse width value is approsimatively given by the formula : tW(OUT) = K · Cx · Rx.(K ≅ 0.45).Taking CLR low breaks this MONOSTABLE STATE. If the next trigger pulse occurs during the MONOSTABLE period it makes the MONOSTABLE period longer. Limit for values of Cx and Rx : Cx : NO LIMIT Rx : V cc < 3.0V 5K Ω to 1M Ω V cc > 3.0V 1K Ω to 1M ΩAll inputs are equipped with protection circuits against static discharge and transient excess voltage.M74HC123DUAL RETRIGGERABLE MONOSTABLE MULTIVIBRATORPIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RDIP M74HC123B1R SOP M74HC123M1RM74HC123RM13TR TSSOPM74HC123TTRM74HC1232/12INPUT AND OUTPUT EQUIVALENT CIRCUITPIN DESCRIPTIONTRUTH TABLEPIN No SYMBOL NAME AND FUNCTION 1,91A, 2A Trigger Inputs (Negative Edge Triggered)2, 101B, 2B Trigger Inputs (Positive Edge Triggered)3, 11 1 CLR 2 CLR Direct Reset LOW and trigger Action at Positive Edge4, 121Q, 2Q Outputs (Active Low)72R X /C X External ResistorCapacitor Connection 13, 51Q, 2Q Outputs (Active High)14, 6 1C X 2C X External Capacitor Connection151R X /C X External ResistorCapacitor Connection 8GND Ground (0V)16VccPositive Supply VoltageM74HC123 SYSTEM DIAGRAMThis logic diagram has not be used to estimate propagation delaysTIMING CHART3/12M74HC1234/12BLOCK DIAGRAM(2) Dx is a clamping diode.The external capacitor is charged to Vcc in the stand-by-state, i.e. no trigger. When the supply voltage is turned off Cx is di scharged mainly trough an internal parasitic diode(see figures). If Cx is sufficiently large and Vcc decreases rapidly, there will be some possibility of damaging the I.C. with a surge current or latch-up. If the voltage supply filter capacitor is large enough and Vcc decrease slowly, the surge current is automatically limited and damage to the I.C. is avoided. The maximum forward current of the parasitic diode is approximately 20 mA. In cases where Cx is large the time taken for the supply voltage to fall to 0.4 Vcc can be calculated as follows : t f > (Vcc - 0.7) x Cx/20mAIn cases where t f is too short an external clamping diode is required to protect the I.C. from the surge current.FUNCTIONAL DESCRIPTION STAND-BY STATEThe external capacitor,Cx, is fully charged to Vcc in the stand-by state. Hence, before triggering,transistor Qp and Qn (connected to the Rx/Cx node) are both turned-off. The two comparators that control the timing and the two reference voltage sources stop operating. The total supply current is therefore only leakage current.TRIGGER OPERATION Triggering occurs when :1 st) A is "LOW" and B has a falling edge;2 nd) B is "HIGH" and A has a rising edge;3 rd) A is "LOW" and B is HIGH and C1 has a rising edge;After the multivibrator has been retriggered comparator C1 and C2 start operating and Qn is turned on. Cx then discharges through Qn. The voltage at the node R/C external falls.When it reaches V REFL the output of comparator C1 becomes low. This in turn reset the flip-flop and Qn is turned off.At this point C1 stops functioning but C2 continues to operate.The voltage at R/C external begins to rise with a time constant set by the external components Rx,Cx.Triggering the multivibrator causes Q to go high after internal delay due to the flip-flop and the gate. Q remains high until the voltage at R/C external rises again to V REFH . At this point C2output goes low and O goes low. C2 stop operating. That means that after triggering when the voltage R/C external returns to V REFH the multivibrator has returned to its MONOSTABLE STATE. In the case where Rx · Cx are large enough and the discharge time of the capacitor and the delay time in the I.C. can be ignored, the width of the output pulse tw (out) is as follows :tW(OUT) = 0.45 Cx · RxRE - TRIGGERED OPERATIONWhen a second trigger pulse follows the first its effect will depend on the state of the multivibrator.If the capacitor Cx is being charged the voltage level of R/C external falls to V REFL again and Q remains High i.e. the retrigger pulse arrives in a time shorter than the period Rx · Cx seconds, the capacitor charging time constant. If the second trigger pulse is very close to the initial trigger pulse it is ineffective ; i.e. the second trigger must arrive in the capacitor discharge cycle to be ineffective;Hence the minimum time for a second trigger to be effective depends on Vcc and Cx RESET OPERATIONCL is normally high. If CL is low, the trigger is not effective because Q output goes low and trigger control flip-flop is reset.Also transistor Op is turned on and Cx is charged quickly to Vcc. This means if CL input goes low the IC becomes waiting state both in operating and non operating state.M74HC1235/12ABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.

The M74HC541 is an inverting buffer.The 3-STATE control gate operates as a two input AND such that if either G1 and G2 are high, all eight output are in the high impedance state. Inorder to enhance PC board layout the M74HC540offer a pinout having inputs and outputs on opposite sides of the package.All inputs are equipped with protection circuits against static discharge and transient excess voltage.M74HC540OCTAL BUS BUFFERWITH 3 STATE OUTPUTS (INVERTED)PIN CONNECTION AND IEC LOGIC SYMBOLSORDER CODESPACKAGE TUBE T & RDIP M74HC540B1R SOP M74HC540M1RM74HC540RM13TR TSSOPM74HC540TTRM74HC5402/10INPUT AND OUTPUT EQUIVALENT CIRCUITPIN DESCRIPTIONTRUTH TABLEX : Don’t CareZ : High ImpedanceABSOLUTE MAXIMUM RATINGSAbsolute Maximum Ratings are those values beyond which damage to the device may occur.
