Texas Instruments SN74HCT138N Logic IC Multiplexer Demultiplexer Signal Switch

Texas Instruments SN74HCT138N is a high-speed CMOS logic integrated circuit (IC) functioning as a 3-to-8 line decoder/demultiplexer. The device, also referred to by alternate description 2993141, operates with a wide voltage range from 4.5 V to 5.5 V and features low power consumption with a typical propagation delay of 18 ns. Designed to implement general-purpose decoding or data routing, this IC is commonly employed in applications such as memory decoding, data routing in digital systems, and signal demultiplexing in communication networks. Its capability to handle a variety of logic levels makes it suitable for interface with TTL and other CMOS logic families in mixed-signal environments.
