The TC74AC139FT is a high-speed CMOS dual 2-to-4 line decoder/demultiplexer manufactured by Toshiba Semiconductor and Storage. This device is designed to accept two binary weighted address inputs (A and B) and enable input (E). When E is low, the decoder converts the binary input address to one of four mutually exclusive outputs. When E is high, all outputs are high. This device is commonly used in memory addressing, data routing, and control logic applications.
