ON 74VHC123AMX

Моностабильный8,1 нс2 В ~ 5,5 В

Overview

The 74VHC123AMX is a dual high speed CMOS retriggerable 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. It 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 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.
