Features

* s Designed specifically for high speed: Memory decoders Data transmission systems s DM74S138 3-to-8-line decoders incorporates 3 enable inputs to simplify cascading and/or data reception s DM74S139 contains two fully independent 2-to-4-line decoders/demultiplexers s Schottky clamped for high perform

Applications

* requiring very short propagation delay times. In high-performance memory systems these decoders can be used to minimize the effects of system decoding. When used with high-speed memories, the delay times of these decoders are usually less than the typical access time of the memory. This means that
