Data transmission systems\nLS138 3-to-8-line decoders incorporates 3 enable inputs to simplify cascading and/or data reception\nLS139 contains two fully independent 2-to-4-line decoders/demultiplexers\nSchottky clamped for high performance\nTypical propagation delay (3 levels of logic)\n?? LS138 21 ns\n?? LS139 21 ns\nTypical power dissipation\n?? LS138 32 mW\n?? LS139 34 mW\nAlternate Military/Aerospace devices (54LS138,54LS139) are available. Contact a National Semicon ductor Sales Office/Distributor for specifications.; General Description\nThese 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 intro duced by the decoder is negligible. | TITexas Instruments 德州儀器美國德州儀器公司 | TI | |
