Dual Non-Retriggerable Monostable Multivibrator  
Features  
General Description  
■ High Speed: t = 8.1ns (Typ.) at V = 5V  
The VHC221A is an advanced high speed CMOS  
Monostable Multivibrator fabricated with silicon gate  
CMOS technology. It achieves the high speed operation  
similar to equivalent Bipolar Schottky TTL while main-  
taining the CMOS low power dissipation. Each multi-  
vibrator features both a negative, A, and a positive, 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 VHC221A can be  
triggered on the positive transition of the clear while A is  
held LOW and B is held HIGH. The VHC221A is non-  
retriggerable, and therefore cannot be retriggered until  
the output pulse times out. The output pulse width is  
determined by the equation:

■ Power down protection is provided on all inputs  
■ Pin and function compatible with 74HC221A  
PW = (Rx)(Cx)

PW is in seconds, R is in ohms, and C is in farads.

An input protection circuit ensures that 0 to 7V can be  
applied to the input pins without regard to the supply  
voltage. This device can be used to interface 5V to 3V  
systems and two supply systems such as battery back  
up. This circuit prevents device destruction due to mis-  
matched supply and input voltages.
