MM54HC27 MM74HC27 Triple 3-Input NOR Gate
January 1988
MM54HC27 MM74HC27
Triple 3-Input NOR Gate
General Description
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-
charge by internal diode clamps to V
