54LS138 Datasheet (National Semiconductor) - (54LS138 / 54LS139) Decoders/Demultiplexers

54LS138, (54LS138 / 54LS139) 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
