CMOS Digital Integrated Circuits Silicon Monolithic  
74HC4538D  
1. Functional Description  
Dual Monostable Multivibrator  
2. General  
The 74HC4538D is a high speed CMOS MONOSTABLE MULTIVIBRATOR fabricated with silicon gate C2MOS  
technology.  
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power  
dissipation.  
There are two trigger inputs, A input (positive edge input), and B input (negative edge input). These inputs are  
valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs.  
After triggering, the output stays in a MONOSTABLE state for the time period determined by the external  
resistor and capacitor (RX, CX). A low level at CD input breaks this STABLE STATE. In the MONOSTABLE  
state, if a new trigger is applied, it makes the MONOSTABLE period longer (retrigger mode).  
Limitations for CX and RX are as follows:  
External capacitor CX.........No limitation  
External resistor RX...........VCC = 2.0 V more than 5 k  
VCC = 3.0 V more than 1 kΩ  
All inputs are equipped with protection circuits against static discharge or transient excess voltage.  
3. Features (Note)  
(1) High speed: tpd = 25 ns (typ.) at VCC = 5 V  
(2) Low power dissipation:  
Standby state: ICC = 4.0 µA (max) at Ta = 25  
Active state: ICC = 350 µA (max) at Ta = 25   
(3) Balanced propagation delays: tPLH tPHL  
(4) Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V  
Note: In the case of using only one circuit, CD should be tied to GND, T1T2QQ should be tied to OPEN, the  
other inputs should be tied to VCC or GND.
