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
