74S138 Datasheet (Fairchild Semiconductor)

74S138, Decoder/Demultiplexer

These Schottky-clamped circuits are designed to be used in high-performance memory-decoding or data-routing applications, requiring very short propagation delay times.

In high-performance memory systems these decoders can be used to minimize the effects of system decoding.
