Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

MM74HCT05 — Hex Inverter (Open Drain)
March 2008
MM74HCT05
Hex Inverter (Open Drain)
Features
■
Open drain for wire-NOR function
■
LS-TTL pinout and threshold compatible
■
Fanout of 10 LS-TTL loads
■
Typical propagation delays:
General Description
The MM74HCT05 is a logic function fabricated by using
advanced silicon-gate CMOS technology, which pro-
vides 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 exter-
nal resistor to perform 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 con-
sumption in existing designs.
