1 / 9 page © 2003 Fairchild Semiconductor Corporation DS009925 www.fairchildsemi.com November 1988 Revised July 2003 74AC138 • 74ACT138 1-of-8 Decoder/Demultiplexer General Description The AC/ACT138 is a high-speed 1-of-8 decoder/demulti- plexer. This device is ideally suited for high-speed bipolar memory chip select address decoding. The multiple input enables allow parallel expansion to a 1-of-24 decoder using just three AC/ACT138 devices or a 1-of-32 decoder using four AC/ACT138 devices and one inverter. Features s ICC reduced by 50% s Demultiplexing capability s Multiple input enable for easy expansion s Active LOW mutually exclusive outputs s Outputs source/sink 24 mA s ACT138 has TTL-compatible inputs Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Connection Diagram Pin Descriptions Logic Symbols IEEE/IEC FACT is a trademark of Fairchild Semiconductor Corporation.
