74LVC139PW-Q100J

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC139PW-Q100J is a dual 2-to-4 line decoder/demultiplexer qualified to AEC-Q100 Grade 1. It features two independent decoders with active LOW enable inputs and mutually exclusive outputs. The device operates on a supply voltage range of 1.2 V to 3.6 V, with overvoltage tolerant inputs up to 5.5 V. It utilizes Schmitt-trigger inputs for noise immunity and supports partial power-down via I_OFF circuitry. Packaged in TSSOP16 (SOT403-1), it functions from -40 °C to +125 °C.
