The TC74HC125A/126A are high speed CMOS QUAD BUS
BUFFERs fabricated with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC125A requires the 3-state control input G to be
set high to place the output into the high impedance state,
whereas the TC74HC126A requires the control input to be set
low to place the output into high impedance.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
