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
www.onsemi.com.

MM74HC125, MM74HC126 — 3-STATE Quad Buffers
February 2008
MM74HC125, MM74HC126
3-STATE Quad Buffers
Features
■
Typical propagation delay: 13ns
■
Wide operating voltage range: 2V–6V
■
Low input current: 1µA maximum
■
Low quiescent current: 80µA maximum (74HC)
■
Fanout of 15 LS-TTL loads
General Description
The MM74HC125 and MM74HC126 are general pur-
pose 3-STATE high speed non-inverting buffers utilizing
advanced silicon-gate CMOS technology. They have
high drive current outputs which enable high speed oper-
ation even when driving large bus capacitances. These
circuits possess the low power dissipation of CMOS
circuitry, yet have speeds comparable to low power
Schottky TTL circuits. Both circuits are capable of driving
up to 15 low power Schottky inputs.
The MM74HC125 require the 3-STATE control input C to
be taken high to put the output into the high impedance
condition, whereas the MM74HC126 require the control
input to be low to put the output into high impedance.
All inputs are protected from damage due to static
discharge by diodes to V
CC
and ground.
