MM74HCT05
Hex Inverter (Open Drain)
General Description
The MM74HCT05 is a logic function fabricated by using
advanced silicon-gate CMOS technology, which provides
the inherent benefits of CMOS--low quiescent power and
wide power supply range. The device is also input and out-
put characteristic and pinout compatible with standard
DM74LS logic families. The MM74HCT05 open drain Hex
Inverter requires the addition of an external resistor to per-
form a wire-NOR function.
All inputs are protected from static discharge damage by
internal diodes to V
CC
and ground.
MM74HCT devices are intended to interface between TTL
and NMOS components and standard CMOS devices.
These parts are also plug-in replacements for LS-TTL
devices and can be used to reduce power consumption in
existing designs.
