74HC243
Datasheet
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.
Features
- Non-inverting 3-state outputs
- 2-way asynchronous data bus communication

- ESD protection:
- HBM EIA/JESD22-A114-B exceeds 2000 V
- MM EIA/JESD22-A115-A exceeds 200 V.
- Multiple package options
- Specified from -40 Cel to +80Cel and from -40 Cel to +125 Cel.
