MM54HCT08/MM74HCT08
Quad 2-Input AND Gate
General Description
The MM54HCT08/MM74HCT08 are logic functions fabri-
cated by using advanced silicon-gate CMOS technology
which provides the inherent benefits of CMOSÐlow quies-
cent power and wide power supply range. These devices
are input and output characteristic and pinout compatible
with standard DM54LS/74LS logic families. All inputs are
protected from static discharge damage by internal diodes
devices. These parts are also plug-in replacements for LS-
TTL devices and can be used to reduce power consumption
in existing designs.
