74VHC123A
Dual Retriggerable Monostable Multivibrator
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)(Cx); where PW is in seconds, R is in ohms, and
C is in farads.
Limits for Rx and Cx are:
External capacitor, Cx No limit
External resistors, Rx VCC = 2.0V, 5 k min
VCC > 3.0V, 1 k min
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.
