CD4555 Dual Binary 1 of 4 Decoder Inverter

The CD4555 is a dual binary 1-of-4 decoder/demultiplexer with non-inverting outputs from the 40xx-series CMOS logic family. Each of the two independent decoders accepts a 2-bit binary address and activates one of four corresponding outputs, making this device suitable for data distribution, memory selection, and channel routing in digital systems.

Each decoder includes a strobe input that enables or disables the output stage, providing additional control for multiplexed bus architectures. With a 3V to 18V supply range and CMOS construction, the CD4555 delivers low power consumption and high noise immunity. The non-inverting outputs are compatible with active-high enable signals common in many peripheral interfaces.
