SN74LV139AD TI Decoder/Demultiplexer | 16-SOIC | Dual 2-to-4, 2V-5.5V

Product Overview

The SN74LV139AD from Texas Instruments is a dual 2-line to 4-line decoder/demultiplexer designed for low-voltage (2V to 5.5V) operation. Housed in a 16-pin SOIC package, this device features two independent decoders, each with active-low outputs and enable inputs. It is ideal for memory decoding, data routing, and general-purpose logic applications where space and power efficiency are critical.
