Each of the two independent circuits takes a 2-bit address input and asserts one of four active-low outputs. ## Automotive temperature range and package Surface-mount only; no through-hole variant in this qualification grade. ## What the output current rating means for your BOM The 5.2 mA per output (both high and low) is typical for HC logic. It will directly drive CMOS inputs, a microcontroller pin, or a low-current indicator.","metaTitle":"SN74HC139QDRQ1 Decoder/Demultiplexer, AEC-Q100, 2V-6V","metaDescription":"TI SN74HC139QDRQ1 dual 1x2:4 decoder/demultiplexer in SOIC-16.

The QDRQ1 variant adds AEC-Q100 automotive qualification and a -40°C to 125°C temperature range, versus the commercial 0°C to 70°C range of the standard SN74HC139DR. The QDRQ1 is the part to specify for automotive or extended-industrial BOMs."},{"question":"Can SN74HC139QDRQ1 be used as a replacement for 74HC139?","answer":"Yes, it is a direct functional replacement for any 74HC139 decoder/demultiplexer in a 16-SOIC footprint. The QDRQ1 adds automotive qualification and extended temperature range, so it can replace the commercial-grade part in any application that does not require a different package."},{"question":"What is the pin configuration of SN74HC139QDRQ1?","answer":"The SN74HC139QDRQ1 uses the standard 16-SOIC pinout for the 74HC139: pins 1–3 and 15 are the first decoder's address and enable inputs; pins 4–7 are its four active-low outputs; pins 9–11 and 13 are the second decoder's inputs; pins 12, 10, 9, 7 are its outputs; pin 8 is GND; pin 16 is VCC.
