74VHC32

Quad 2-Input OR Gate

General Description

The VHC32 is an advanced high speed CMOS 2-Input OR

Gate 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.

The internal circuit is composed of 4 stages including buffer

output, which provide high noise immunity and stable out-

put. An input protection circuit ensures that 0V 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.

Features

s High Speed:

tPD = 3.8 ns (typ) at VCC = 5V

s Low Power Dissipation:

ICC = 2 µA (Max) at TA = 25°C

s High Noise Immunity: VNIH = VNIL = 28% VCC (Min)

s Power down protection is provided on all inputs

s Low Noise: VOLP = 0.8V (Max)
