Texas Instruments SN74HC138D Logic IC 3-to-8 line decoder TTL-compatible

Texas Instruments SN74HC138D is identified by the alternate description 2994352. This logic IC is a 3-to-8 line decoder/demultiplexer that is TTL-compatible, offering efficient low-power operation with high-noise immunity. The SN74HC138D features three enable inputs and provides 8 active-low outputs, facilitating the expansion of binary-coded inputs into one of 8 mutually exclusive outputs. With a typical supply voltage range of 2 V to 6 V and a maximum input transition time of 100 ns, it is ideal for various engineering applications such as data demultiplexing, memory addressing, and decoding of logic inputs in digital circuits. Its operational reliability ensures it is suitable for integration in complex logic networks within professional and industrial electronics systems.
