HD74HC221  
Dual Monostable Multivibrators (with Schmitt Trigger Input)  
REJ03D0591–0200  
(Previous ADE-205-468)  
Rev.2.00  
Jan 31, 2006  
Description  
Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used  
as an inhibit. Also included is a clear input that when taken low resets the one shot. The HD74HC221 can be triggered  
on the positive transition of the clear while A is held low and B is held high.  
This device is a non-retriggerable, and therefore cannot be retriggered until the output pulse times out.  
The output pulse equation is simply:  
tW = 0.7·(Rext)·(Cext)  
Features  
High Speed Operation  
High Output Current: Fanout of 10 LSTTL Loads  
Wide Operating Voltage: VCC = 2 to 6 V  
Low Input Current: 1 µA max  
Low Quiescent Supply Current
