SN74AHC138PW TI Decoder/Demultiplexer | 16-TSSOP | 3-to-8 Line, 2V to 5.5V

Product Overview

The SN74AHC138PW is a high-performance 3-to-8 line decoder/demultiplexer from Texas Instruments, designed for low-power and high-speed applications. Housed in a compact 16-TSSOP package, this device is ideal for memory decoding, data routing, and control logic in modern electronic systems. It operates over a wide voltage range of 2V to 5.5V, making it compatible with both 3.3V and 5V logic levels. The SN74AHC138PW features three enable inputs (G1, G2A, G2B) for flexible control, and its outputs are active low, providing direct interface with most microcontrollers and digital systems.
