SN74HC139QDRQ1 TI Decoder/Demux | 16-SOIC | Dual 2-to-4, -40°C to 125°C

Product Overview

The SN74HC139QDRQ1 is a dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed for automotive applications. It features two independent decoders, each accepting two binary inputs (A0, A1) and providing four mutually exclusive active-low outputs (Y0–Y3). The device is housed in a 16-pin SOIC package and operates over a wide temperature range of -40°C to 125°C, making it suitable for harsh automotive environments. It is AEC-Q100 qualified and supports 2V to 6V supply voltage, with typical propagation delays of 12ns at 5V.
