Texas Instruments SN74AHC138 3-Line To 8-Line Decoder / Demultiplexer SN74AHC138DRG4

The SN74AHC138 is a 3-line to 8-line decoder/demultiplexer designed for high-speed memory decoding and data routing applications. It operates within a voltage range of 2V to 5.5V, making it suitable for various digital logic applications. The device features three enable inputs, which facilitate cascading and data reception, thereby enhancing flexibility in circuit design. This decoder is optimized for performance, with propagation delay times that are typically less than the access time of high-speed memories, ensuring minimal system delay. The SN74AHC138 also boasts robust latch-up performance exceeding 250mA and ESD protection levels of 2000V for the Human-Body Model and 1000V for the Charged-Device Model, ensuring reliability in demanding environments. Available in multiple package types, including SOIC, TSSOP, and PDIP, the SN74AHC138 is a versatile choice for engineers looking to implement efficient decoding solutions in their projects.
