MM74HC221A  
Dual Non-Retriggerable Monostable Multivibrator  
is in seconds, R is in ohms, and C is in farads. All inputs  
are protected from damage due to static discharge by  
diodes to VCC and ground.  
General Description  
The MM74HC221A high speed monostable multivibrators  
(one shots) utilize advanced silicon-gate CMOS technol-  
ogy. They feature speeds comparable to low power Schot-  
tky TTL circuitry while retaining the low power and high  
noise immunity characteristic of CMOS circuits.  
Features  
■ Typical propagation delay: 40 ns  
■ Wide power supply range: 2V–6V  
■ Low quiescent current: 80 µA maximum (74HC Series)  
■ Low input current: 1 µA maximum  
■ Fanout of 10 LS-TTL loads  
Each multivibrator features both a negative, A, and a posi-  
tive, B, transition 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 MM74HC221A  
can be triggered on the positive transition of the clear while  
A is held LOW and B is held HIGH.  
■ Simple pulse width formula T = RC  
■ Wide pulse range: 400 ns to ∞ (typ)  
■ Part to part variation: ±5% (typ)  
The MM74HC221A is a non-retriggerable, and therefore  
cannot be retriggered until the output pulse times out.  
Pulse width stability over a wide range of temperature and  
supply is achieved using linear CMOS techniques. The out-  
put pulse equation is simply: PW = (REXT) (CEXT); where  
■ Schmitt Trigger A & B inputs enable infinite signal input
