Texas Instruments SN74AHCT139 Dual 2-Line To 4-Line Decoders / Demultiplexers SN74AHCT139DR

The SN74AHCT139 is a dual 2-line to 4-line decoder/demultiplexer designed for operation within a supply voltage range of 4.5 V to 5.5 V. It is optimized for high-speed memory decoding and data transmission applications, featuring very short propagation delay times that minimize system decoding effects. The device includes two enable inputs, facilitating cascading and data reception. This component is TTL-voltage compatible and has fully buffered inputs, ensuring minimal load on the driving circuit. It also boasts robust latch-up performance exceeding 250 mA and ESD protection that surpasses JESD standards, with ratings of 2000 V for the Human-Body Model and 1000 V for the Charged-Device Model. The operating temperature range is from -40¬8C to 85¬8C, making it suitable for a variety of environments. The SN74AHCT139DR variant is available in a 16-pin SOIC package, suitable for tape and reel packaging.
