SN74LVC139AGQNR TI Decoder/Demux | 20-BGA MICROSTAR JUNIOR (4X3) | Dual 2-to-4, 1.65-3.6V

Product Overview

The SN74LVC139AGQNR is a dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed for low-voltage, high-speed operation. Housed in a compact 20-ball BGA MICROSTAR JUNIOR (4x3 mm) package, it is ideal for space-constrained applications. The device operates over a wide supply voltage range of 1.65V to 3.6V, making it compatible with various logic families. Each decoder has two active-low enables and four active-low outputs, providing flexibility in address decoding and signal routing.
