DM74LS138 Decoders/Demultiplexers

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 mem.
