DM74LS156N, Dual 2-to-4-Line Decoder,Demultiplexer, DIP-16

The DM74LS156N is a dual 2-to-4-line decoder/demultiplexer designed for address decoding, data distribution, and function selection in digital logic circuits. It features open-collector outputs, making it suitable for wired-AND logic and applications requiring multiple ICs to share outputs. Operating within a voltage range of 4.75V to 5.25V, the DM74LS156N ensures reliable performance in TTL-based systems. Each decoder section operates independently, providing versatile data routing and control capabilities. The active-low enable inputs allow for flexible gating and expansion in complex digital designs. With its DIP-16 package, the DM74LS156N is ideal for use in address decoding, memory selection, and control logic applications.
