Features

* Y Y Y Y Y Y Y Designed specifically for high speed Memory decoders Data transmission systems LS138 3-to-8-line decoders incorporates 3 enable inputs to simplify cascading and or data reception LS139 contains two fully independent 2-to-4-line decoders demultiplexers Schottky clamped for high pe

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 the e
