Texas Instruments Signal Switches, Multiplexers, Decoders SN74HC139NE4

The SN74HC139NE4 is a dual 2-line to 4-line decoder/demultiplexer designed for high-speed memory decoding and data transmission applications. It operates within a voltage range of 2 V to 6 V and features low power consumption, with a maximum supply current of 80 OºA. The device can drive up to 10 LSTTL loads and provides a typical propagation delay of 10 ns. It includes two enable inputs to facilitate cascading and data reception, enhancing its versatility in complex circuit designs. The outputs are configured such that when the strobe input is active, all outputs are set high, while only the selected output is low when the strobe is inactive. The SN74HC139NE4 is available in a 16-pin PDIP package, making it suitable for various applications requiring efficient signal routing and control.
