General description

The 74HC243 is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). The 74HC243 is specified in compliance with JEDEC standard no. 7A.

The 74HC243 is a quad bus transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74HC243 is designed for 4-line asynchronous 2-way data communications between data buses.

The output enable inputs (OEA and OEB) can be used to isolate the buses.

The 74HC243 is similar to the 74HC242 but has non-inverting (true) outputs.
