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.

• Demultiplexing Capability

• Multiple Input Enable for Easy Expansion

• Active LOW Mutually Exclusive Outputs

• Outputs Source/Sink 24 mA

• ′ACT138 Has TTL Compatible Inputs
