General Description
The MM74HCT32 is a logic function fabricated by using
advanced silicon-gate CMOS technology, which pro-
vides the inherent benefits of CMOS—low quiescent
power and wide power supply range. This device is input
and output characteristic and pin-out compatible with
standard 74LS logic families. All inputs are protected
from static discharge damage by internal diodes to V
CC
and ground.
MM74HCT devices are intended to interface between
TTL and NMOS components and standard CMOS
devices. These parts are also plug-in replacements for
LS-TTL devices and can be used to reduce power
consumption in existing designs.

Absolute Maximum Ratings
(1)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
