SL74LS138 3-to-8-Line Decoder/Demultiplexer This schottky-clamped TTL MSI circuit is designed to be used in high-performance memory-decording or data-routing applications requiring very short propagation delay time. In high-performance memory systems this decode can be used to minimize the effects of system decoding. When employed with high-speed memories u.
