1-OF-8 DECODER/
DEMULTIPLEXER
The MC54/74F138 is a high speed 1-of-8 Decoder/Demultiplexer. This de-
vice is ideally suited for high speed bipolar memory chip select address de-
coding. The multiple input enables allow parallel expansion to a 1-of-24 de-
coder using just three F138 devices or to a 1-of-32 decoder using four F138s
and one inverter.
Demultiplexing Capability
Multiple Input Enable for Easy Expansion
Active Low Mutually Exclusive Outputs
Input Clamp Diodes Limit High-Speed Termination Effects
