DESCRIPTION  
The M54/74HC4538 is a high speed CMOS DUAL  
MONOSTABLEMULTIVIBRATOR fabricated insili-  
con gate C2MOS technology. It has the same high  
speed performance of LSTTL combined with true  
CMOS low power consumption. Each multivibrator  
features both a negative, A, and a positive, B, edge  
triggered input, either of which can be used as an in-  
hibit input. Also included is a clear input that when  
taken low resets the one shot. The monostable  
multivibrators are retriggerable. That is,they may be  
triggered reapeatedly while their outputs are gener-  
ating a pulse and the pulse will be extended. Pulse  
width stability over a wide range of temperature and  
supply is achieved using linear CMOS techniques.  
The output pulse equation is simply  
:
PW = 0.7 (R)(C) where PW is in seconds, R in  
Ohms, and C is in Farads.  
NC =  
All inputs are equipped with protection circuits  
against static discharge and transient excess volt-  
age.
