It contains two independent circuits, each decoding a 2-bit binary input to four mutually exclusive active-low outputs. Operates from 3V to 18V single or dual supply — the wide range covers battery-powered 3.3V portable gear through industrial 12V rails. Each output sources or sinks 6.8mA typical, enough to drive standard CMOS or TTL loads without external buffers in low-speed address decoding. ## Package and board fit The narrow-body SOIC footprint is common across 4000B logic — a single PCB land pattern serves multiple decoder variants in the family.","metaTitle":"Texas Instruments CD4556BMT Decoder/Demultiplexer, 16-SOIC","metaDescription":"Texas Instruments CD4556BMT active 4000B decoder/demux, 1 x 2:4 circuit, 3V-18V supply, -55°C to +125°C, 16-SOIC.
