Texas Instruments Integrated Circuits (ICs) - Logic - Signal Switches, Multiplexers, Decoders SN74LVC139AGQNR

The SN74LVC139AGQNR is a dual 2-line to 4-line decoder/demultiplexer designed for operation within a supply voltage range of 1.65 V to 3.6 V. It can accept input voltages up to 5.5 V, making it suitable for mixed-voltage applications. The device features a maximum propagation delay of 6.2 ns and provides low output ground bounce and undershoot characteristics, with typical values of less than 0.8 V and greater than 2 V, respectively, at a supply voltage of 3.3 V. This decoder/demultiplexer includes fully buffered inputs, allowing it to function effectively in systems that utilize both 3.3 V and 5 V devices. It is also designed to exceed latch-up performance standards and offers robust ESD protection, rated at 2000 V for the human body model and 200 V for the machine model. The operating temperature range is specified from -40 °C to 85 °C, ensuring reliability in various environmental conditions. The SN74LVC139AGQNR is available in a 20-BGA MicroStar Junior package, making it suitable for compact designs.
