It takes four binary address inputs and drives one of sixteen active-low outputs low. ## Sourcing and lifecycle — active, no LTB pressure There is no last-time-buy notice or obsolescence risk on this line. The part is ROHS3 compliant, so it passes modern environmental requirements without needing a waiver. ## Output drive and what it means for the bus Each output can source or sink 4 mA (high and low). That is enough to drive a CMOS logic input or a low-power LED indicator directly, but not enough to drive a relay coil or a long backplane trace without a buffer. ## Package and board fit The part comes in a 24-SOIC wide-body package (0.295-inch body width, 7.50 mm). That is a standard footprint shared by many 24-pin SOIC logic parts. The surface-mount package suits automated assembly lines. No special handling required beyond standard SMD reflow profiles.","metaTitle":"CD74HCT154M 74HCT Decoder/Demultiplexer, 1x4:16, 24-SOIC","metaDescription":"CD74HCT154M 74HCT 1-of-16 decoder/demultiplexer in 24-SOIC. 4.5V–5.5V supply, -55°C to 125°C.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Decoder/Demultiplexer","Series":"74HCT","Circuit":"1 x 4:16","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"24-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Independent Circuits":"1","Operating Temperature":"-55°C ~ 125°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"24-SOIC","Current - Output High, Low":"4mA, 4mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.46","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.46000","currency":"USD"},{"qty":10,"price":"$1.30400","currency":"USD"},{"qty":25,"price":"$1.23760","currency":"USD"},{"qty":100,"price":"$1.01660","currency":"USD"},{"qty":250,"price":"$0.95036","currency":"USD"},{"qty":500,"price":"$0.83984","currency":"USD"},{"qty":1000,"price":"$0.66303","currency":"USD"},{"qty":2500,"price":"$0.62550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8ce1fa73a7a20b163037f3a2fd1cdfde.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the CD74HCT154M?","answer":"It decodes four address inputs into sixteen active-low outputs, operates from 4.5V to 5.5V, and is rated for -55°C to 125°C."},{"question":"Is CD74HCT154M equivalent to 74HC154?","answer":"The CD74HCT154M is the HCT (high-speed CMOS with TTL-compatible input thresholds) version of the 74HC154.
