CC  
The M74HC4538 is a high speed CMOS monostable  
multivibrator fabricated with silicon gate C2MOS  
technology.  
■ Wide output pulse width range:

■ Pin and function compatible with  
Each multivibrator features both a negative A, and a  
positive B, edge triggered input, either of which can be  
used as an inhibit input. Also included is a clear input  
that when taken low resets the one shot. The  
74 series 4538  
monostable multivibrators are retriggerable. That is,  
they may be triggered repeatedly while their outputs are  
generating 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 Omhs and C is in Farads.  
All the inputs are equipped with protection circuits  
against static discharge and transient excess voltage.
