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.

General Description
The VHCT08A is an advanced high speed CMOS 2
Input AND Gate fabricated with silicon gate CMOS tech-
nology. 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.
Protection circuits ensure that 0V to 7V can be applied to
the input pins without regard to the supply voltage and to
the output pins with V
CC
=
0V. These circuits prevent
device destruction due to mismatched supply and input/
output voltages. This device can be used to interface 3V
to 5V systems and two supply systems such as battery
backup.
