MM74HCT32
Quad 2-Input OR Gate
General Description
The MM74HCT32 is a logic function fabricated by using
advanced silicon-gate CMOS technology, which provides
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.
