Texas Instruments SN74AHCT139 Dual 2-Line To 4-Line Decoders / Demultiplexers SN74AHCT139DG4

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 delay. The device includes two enable inputs, facilitating cascading and data reception. This component is TTL-compatible and has fully buffered inputs, ensuring that each input presents a normalized load to its driving circuit. The active-low enable input can also function as a data line in demultiplexing scenarios. The SN74AHCT139 exhibits robust latch-up performance exceeding 250 mA and offers ESD protection that surpasses JESD standards, making it suitable for various applications requiring reliability and durability. The operating temperature range for this device is from -40¬8C to 85¬8C, and it is available in multiple package types, including SOIC and TSSOP.
