MM74HC125/MM74HC126
3-STATE Quad Buffers
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.
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 dis-
charge by diodes to V
CC
and ground.
