MC74AC138, MC74ACT138

1-of-8

Decoder/Demultiplexer

The MC74AC138/74ACT138 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 MC74AC138/74ACT138 devices or a

1−of−32 decoder using four MC74AC138/74ACT138 devices and one

inverter.
