74LVC1G139DCURG4 TI Decoder/Demux | 8-VSSOP | 1.65-5.5V, 2-to-4 Line

Product Overview

The 74LVC1G139DCURG4 from Texas Instruments is a single 2-to-4 line decoder/demultiplexer designed for 1.65-V to 5.5-V VCC operation. It is fabricated with advanced low-voltage CMOS technology to achieve high speed and low power consumption. The device features two address inputs (A0, A1), an active-low enable input (E), and four active-low outputs (Y0–Y3). When the enable input is high, all outputs are forced high regardless of the address inputs. This device is ideal for memory decoding, data routing, and general logic functions in space-constrained applications.
