DM74ALS138 3 to 8 Line Decoder/Demultiplexer September 1986 Revised February 2000 DM74ALS138 3 to 8 Line Decoder/Demultiplexer General Description 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. 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 effective system delay introduced by the decoder is negligible. The DM74ALS138 decodes one-of-eight lines, based upon the...
