MM54HC27/MM74HC27
Triple 3-Input NOR Gate
General Description
These NOR gates utilize advanced silicon-gate CMOS technology,
to achieve operating speeds similar to LS-TTL gates
with the low power consumption of standard CMOS integrated
circuits. All gates have buffered outputs, providing
high noise immunity and the ability to drive 10 LS-TTL loads.
The 54HC/74HC logic family is functionally as well as pinout
compatible with the standard 54LS/74LS logic family.
All inputs are protected from damage due to static discharge
by internal diode clamps to VCC and ground.
