CD4556 1-to-4 line decoder

The CD4556 DIP Dual 1-To-4 Line Decoder/Demultiplexer is a CMOS IC that provides two independent 1-to-4 decoders for signal routing or control line expansion. With two control inputs (A and B), it selects one of four output lines (Y0 to Y3) for efficient data distribution. Ideal for signal multiplexing, address decoding, and control systems, the CD4556 operates within a wide voltage range and offers low power consumption for embedded systems and digital circuits.
