74138 Description
DM74LS138 * DM74LS139 Decoder/Demultiplexer August 1986 Revised March 2000 DM74LS138 * DM74LS139 Decoder/Demultiplexer General Descr.
These Schottky-clamped circuits are designed to be used in high-performance memory-decoding or data-routing applications, requiring very short propaga.
74138 Features
* s Designed specifically for high speed: Memory decoders Data transmission systems s DM74LS138 3-to-8-line decoders incorporates 3 enable inputs to simplify cascading and/or data reception s DM74LS139 contains two fully independent 2-to-4-line decoders/demultiplexers s Schottky clamped for high perfo
74138 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
