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.
