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.

Ordering Code:

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
