  3. Oct 26, 2018 · 74LS138 Decoder IC. 74LS138 Decoder Pinout. 74LS138 is a member from ‘74xx’family of TTL logic gates. The chip is designed for decoding or de-multiplexing applications and comes with 3 inputs to 8 output setup. The design is also made for the chip to be used in high-performance memory-decoding or data-routing applications, requiring very ...

  4. TECHNICAL DATA IN74LS138 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.

  5. The LSTTL/MSI SN54/74LS138 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 ex- pansion to a 1-of-24 decoder using just three LS138 devices or to a 1-of-32 decoder using four LS138s and one inverter.
