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 = (R_x)(C_x); where PW is in seconds, R is in ohms, and

Features
