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

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)
s Pin and Function Compatible with 74HC32
