54F 74F138
1-of-8 Decoder Demultiplexer
General Description
The ’F138 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 ’F138 devices or a 1-of-32 decoder using four ’F138
devices and one inverter
Features
