MM54HC27/MM74HC27
Triple 3-Input NOR Gate
General Description
Features
Y
These NOR gates utilize advanced silicon-gate CMOS tech-
nology, to achieve operating speeds similar to LS-TTL gates
with the low power consumption of standard CMOS inte-
grated 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 pin-
out compatible with the standard 54LS/74LS logic family.
All inputs are protected from damage due to static dis-
Typical propagation delay: 8 ns
