Ordering Information
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 output characteristic and pinout compatible
with standard DM74LS logic families. The MM74HCT05
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
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.

Absolute Maximum Ratings
(1)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
