74VHC123A  
Dual Retriggerable Monostable Multivibrator  
An input protection circuit ensures that 0 to 7V can be  
applied to the input pins without regard to the supply volt-  
age. This device can be used to interface 5V to 3V systems  
and two supply systems such as battery back up. This cir-  
cuit prevents device destruction due to mismatched supply  
and input voltages.  
General Description  
The VHC123A 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 maintaining the  
CMOS low power dissipation. Each multivibrator 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 VHC123A can be triggered on the positive  
transition of the clear while A is held low and B is held high.  
The output pulse width is determined by the equation:  
PW = (Rx)(Cx); where PW is in seconds, R is in ohms, and
