General Description
These are general purpose TRI-STATE high speed non-in-
verting buffers utilizing advanced silicon-gate CMOS tech-
nology They have high drive current outputs which enable
high speed operation even when driving large bus capaci-
tances 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 MM54HC125MM74HC125 require the TRI-STATE
control input C to be taken high to put the output into the
high impedance condition
whereas the MM54HC126
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 VCC and ground
