SN74HC138DR | TI 3-to-8 Line Decoder | High-Speed ​​CMOS Logic Chip

Product Overview

     The SN74HC138DR from Texas Instruments (TI) is a high-speed 3-to-8 line decoder/demultiplexer built using advanced CMOS technology. It operates from a wide 2V to 6V supply voltage and is TTL/CMOS logic compatible, providing active-low outputs.

     Three binary address inputs (A0, A1, A2) select one of eight outputs, while three enable inputs (G1, G2A, G2B) allow cascading, address decoding, and data routing applications. This device offers high-speed switching, low static power consumption, and excellent noise immunity, making it ideal for microcontroller address decoding, data multiplexing, and logic signal selection. Packaged in SOIC-16 (DR), the SN74HC138DR meets RoHS / Pb-Free / REACH compliance and is suitable for industrial, embedded, and communication systems.
