MM54HC7266 MM74HC7266 Quad 2-Input
Exclusive NOR Gate
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 stan-
dard CMOS integrated circuits These gates are fully buff-
ered and have a fanout of 10 LS-TTL loads The MM54HC
MM74HC logic family is functionally as well as pin out com-
patible with the standard 54LS 74LS logic family However
unlike the ’LS266 which is an open collector gate the
’HC266 has standard CMOS push-pull outputs All inputs
are protected from damage due to static discharge by inter-
nal diode clamps to V_CC and ground
