Texas Instruments SN54HC139 Dual 2-Line To 4-Line Decoders/Demultiplexers SN54HC139J

The SN54HC139J 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 circuit design. The outputs are configured such that when the strobe input is active, all outputs are set to high, while only the selected output is low when the strobe is inactive. The SN54HC139J is available in a 16-pin CDIP package, making it suitable for various applications requiring compact and efficient decoding solutions.
