www.DataSheet4U.com SN74LS138 1-of-8 Decoder/ Demultiplexer The LSTTL / MSI SN74LS138 is a high speed 1-of-8 Decoder / Demultiplexer. This device is ideally suited for high speed bipolar memory chip select address decoding. The multiple input enables allow parallel expansion to a 1-of-24 decoder using just three LS138 devices or to a 1-of-32 decoder using four LS138s and one inverter. The LS138 is fabricated with the Schottky barrier diode process for high speed and is completely compatible wit.

DM74LS138 • DM74LS139 Decoder/Demultiplexer August 1986 Revised March 2000 DM74LS138 • DM74LS139 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 les.
