MC74AC138ML1-MC74ACT138M
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
