74AC138 • 74ACT138 1-of-8 Decoder/Demultiplexer November 1988 Revised August 2000 74AC138 • 74ACT138 1-of-8 Decoder/Demultiplexer General Description The AC/ACT138 is a high-speed 1-of-8 decoder/demultiplexer. 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.
