MM54HC05 MM74HC05 Hex Inverter (Open Drain)
January 1988
MM54HC05 MM74HC05
Hex Inverter (Open Drain)
General Description
The MM54HC05 MM74HC05 are logic functions fabricated
by using advanced silicon-gate CMOS technology which
provides the inherent benefits of CMOS low quiescent
power and wide power supply range These devices are
also functionally and pin-out compatible with standard
DM54LS DM74LS logic families
The MM54HC05
MM74HC05 open drain Hex Inverter requires the addition of
an external resistor to perform a wire-NOR function
All inputs are protected from static discharge damage by
internal diodes to V
CC
and ground
