MM74HC125/MM74HC126

3-STATE Quad Buffers

condition, whereas the MM74HC126 require the control

input to be low to put the output into high impedance.

General Description

The MM74HC125 and MM74HC126 are general purpose

3-STATE high speed non-inverting buffers utilizing

advanced silicon-gate CMOS technology. They have high

drive current outputs which enable high speed operation

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 cir-

cuits. Both circuits are capable of driving up to 15 low

power Schottky inputs.

All inputs are protected from damage due to static dis-

charge by diodes to V_CCand ground.

Features

■ Typical propagation delay: 13 ns

■ Wide operating voltage range: 2–6V

■ Low input current: 1 µA maximum

■ Low quiescent current: 80 µA maximum (74HC)

■ Fanout of 15 LS-TTL loads

The MM74HC125 require the 3-STATE control input C to

be taken high to put the output into the high impedance
