DESCRIPTION

The M54/74HC242/243 are high speed CMOS

QUAD

BUS

TRANSCEIVER

(3-STATE)

FABRICATED IN SILICON GATE C²MOS

technology. They have the same high speed

performance of LSTTL combined with true CMOS

low power consumption. The HC242/243 are 3

STATE bi-directional inverting and non-inverting

buffers and are intended for two-way asynchronous

communication between data buses. They are high

drive current outputs which enable high speed

operation when driving large bus capacitances.

Each device has one active high enable (GBA), and

one active low enable (GAB). GBA enables the A

outputs and GAB enables the B outputs. All inputs

are equipped with protection circuits against static

discharge and transient excess voltage.
