MM74HCT08
Quad 2-Input AND Gate
General Description
The MM74HCT08 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 pinout 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.
