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
s Demultiplexing capability
s Multiple input enable for easy expansion
s Active LOW mutually exclusive outputs
