Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

Pin and Function Compatible with 74HC32
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 output. An input protection circuit ensures that 0V
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 bat-
tery back up. This circuit prevents device destruction due
to mismatched supply and input voltages.
