DESCRIPTION

The M54HC125 is an high speed CMOS QUAD

BUFFER (3-STATE) fabricated with silicon gate

The device requires the 3-STATE control input G

to be set high to place the output into the high

impedance state.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
