It contains two independent 1 x 2:4 circuits, each with active-high outputs. The part operates across a wide supply range of 3V to 18V and is specified over the full military temperature range of -55°C to 125°C, making it suitable for industrial, avionics, and downhole applications where the logic level must span a variable rail and the ambient temperature is extreme. ## CMOS construction and dual-supply source The CD4555BM is a CMOS device (, 4000B series). The voltage supply source is listed as dual supply, which refers to the device's internal architecture — it can decode an active-HIGH or active-LOW enable and address inputs referenced to VDD and VSS, not that it requires two separate power rails. Standard connection is a single supply between VDD (3V to 18V) and VSS (ground). ## Sourcing and lifecycle The CD4555BM carries an Active product status with no NRND or EOL flags. It is ROHS3 compliant.","metaTitle":"TI CD4555BM 4000B Decoder/Demultiplexer, 1x2:4, 3V-18V","metaDescription":"Active TI CD4555BM decoder/demultiplexer, 1 x 2:4 circuit, 3V to 18V supply, -55°C to 125°C. 16-SOIC.","metaKeywords":null},"attributes":{"series":"4000B","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Decoder/Demultiplexer","Series":"4000B","Circuit":"1 x 2:4","Package":"Tube","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":"$1.09","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.09000","currency":"USD"},{"qty":10,"price":"$0.97900","currency":"USD"},{"qty":25,"price":"$0.92880","currency":"USD"},{"qty":100,"price":"$0.76310","currency":"USD"},{"qty":250,"price":"$0.71332","currency":"USD"},{"qty":500,"price":"$0.63038","currency":"USD"},{"qty":1000,"price":"$0.49767","currency":"USD"},{"qty":2500,"price":"$0.46950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/24a833d47520fe082280a01697516dc1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CD4555BM a CMOS device?","answer":"Yes, CD4555BM is part of the 4000B series, which is a CMOS logic family."},{"question":"What is the difference between CD4555BM and CD4555BE?","answer":"The difference is the package.
