DESCRIPTION
The M74HC242 is an high speed CMOS QUAD
BUS TRANSCEIVER (3-STATE) fabricated with
silicon gate C2MOS technology.
The M74HC242 is a 3-state bidirectional inverting
buffer and is intended for two way asynchronous
communication between data buses. It has high
drive current outputs which enable high speed
operation when driving large bus capacitance.
The device has one active high enable (GBA), and
one active low enable (GAB).
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
