74VHC123A

Dual Retriggerable Monostable Multivibrator

Features

General Description

■ High Speed: t = 8.1ns (Typ.) at T = 25°C

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 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 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

■ Low Power Dissipation: I = 4µA (Max) at T = 25°C

■ Active State: I = 600µA (Max.) at T = 25°C

■ High Noise Immunity: V

= V

= 28% V (Min.)

NIH

NIL CC

■ Power down protection is provided on all inputs

■ Pin and function compatible with 74HC123A

determined by the equation: PW = (R )(C ); where PW

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

Limits for R and C are:

External capacitor, C : No limit

External resistors, R : V = 2.0V, 5 kΩ min

> 3.0V, 1 kΩ min

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.
