MM54HC266A/MM74HC266A Quad 2-Input
Exclusive NOR Gate (Open Drain)
General Description
This exclusive NOR gate utilizes advanced silicon-gate
CMOS technology to achieve operating speeds similar to
equivalent LS-TTL gates while maintaining the low power
consumption and high noise immunity characteristic of standard
CMOS integrated circuits. These gates are fully buffered
and have a fanout of 10 LS-TTL loads. The MM54HC/
MM74HC 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 discharge by internal
diode clamps to VCC and ground.
