DESCRIPTION

The M74HC243 is an high speed CMOS QUAD

BUS TRANSCEIVER (3-STATE) fabricated with

silicon gate C2MOS technology.

The

M74HC243

is

a

3-state

bidirectional

non-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.
