SL74LS138 Datasheet - System Logic Semiconductor

SL74LS138 3-to-8-Line Decoder/Demultiplexer This schottky-clamped TTL MSI circuit is designed to be used in high-performance memory-decording or data-routing applications requiring very short propagation delay time.

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

When employed with high-speed memories utilizing a fast enable circuit the delay times of this decorder and the enable time of the memory are usually less than the typical access t
