DESCRIPTION

The 74VHCT125A is an advanced high-speed

CMOS QUAD BUS BUFFERS fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology.

The device requires the 3-STATE control input G

to be set high to place the output in to the high

impedance state.

Power down protection is provided on all inputs

and outputs and 0 to 7V can be accepted on

inputs with no regard to the supply voltage. This

device can be used to interface 5V to 3V since all

inputs are equipped with TTL threshold.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
