It takes a 2-bit binary address input and activates one of four active-low outputs on each of the two independent decoder sections. This part is the go-to for address decoding in memory-mapped I/O, routing control signals in industrial PLC backplanes, or fanning out a single data stream to multiple channels in instrumentation front-ends. The wide 3V to 18V supply range means it can sit on a 5V or 12V rail without a level translator, and the -55°C to 125°C temperature grade qualifies it for avionics, downhole tools, and outdoor telecom cabinets where the ambient swings hard. ## Two decoders in one 16-SOIC — what that saves you Two independent 1:4 decoder circuits in a single 16-SOIC package. Each decoder section drives 6.8 mA source or sink at the outputs. ## Sourcing and lifecycle — still a current-production part The CD4556BM96 carries an Active product status with ROHS3 compliance. For a BOM line that needs a 4000B decoder in SOIC, this is a low-risk, production-ready choice. The 'M96' suffix indicates the 16-SOIC tape-and-reel variant; the same die is also available in other packages if your assembly line prefers tubes or trays.","metaTitle":"CD4556BM96 Decoder/Demultiplexer, 1 x 2:4, 16-SOIC","metaDescription":"TI CD4556BM96 4000B series decoder/demux, 1 x 2:4 circuit, 3V-18V supply, -55°C to 125°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"4000B","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Decoder/Demultiplexer","Series":"4000B","Circuit":"1 x 2:4","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 18V","Independent Circuits":"2","Operating Temperature":"-55°C ~ 125°C","Voltage Supply Source":"Dual Supply","Supplier Device Package":"16-SOIC","Current - Output High, Low":"6.8mA, 6.8mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.52","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.52000","currency":"USD"},{"qty":10,"price":"$0.44900","currency":"USD"},{"qty":25,"price":"$0.41920","currency":"USD"},{"qty":100,"price":"$0.33540","currency":"USD"},{"qty":250,"price":"$0.31144","currency":"USD"},{"qty":500,"price":"$0.26352","currency":"USD"},{"qty":1000,"price":"$0.20363","currency":"USD"},{"qty":2500,"price":"$0.18566","currency":"USD"},{"qty":5000,"price":"$0.17368","currency":"USD"},{"qty":12500,"price":"$0.16950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/24a833d47520fe082280a01697516dc1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CD4556BM96 a direct replacement for CD4556B?","answer":"The CD4556BM96 is the surface-mount (SOIC) version of the same 4000B dual 1:4 decoder.
