It accepts nine active-low inputs and encodes the highest-priority active input into a 4-line BCD output. ## Military temperature range — what it means for the BOM Rated for -55°C to 125°C, this encoder is specified for avionics, satellite, downhole instrumentation, and other high-reliability environments where commercial or industrial temperature parts would drift out of spec. The 4 mA output current at both high and low levels is modest — plan on buffering if driving long traces or multiple CMOS loads. ## Sourcing and lifecycle It is ROHS3 compliant.","metaTitle":"Texas Instruments CD74HCT147E Priority Encoder, 1 x 10:4","metaDescription":"Active Texas Instruments CD74HCT147E 10-line to 4-line priority encoder. 4.5V-5.5V supply, -55°C to 125°C range, 16-DIP through-hole.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Priority Encoder","Series":"74HCT","Circuit":"1 x 10:4","Package":"Tube","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","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":"16-PDIP","Current - Output High, Low":"4mA, 4mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.81000","currency":"USD"},{"qty":10,"price":"$0.71700","currency":"USD"},{"qty":25,"price":"$0.67360","currency":"USD"},{"qty":100,"price":"$0.54980","currency":"USD"},{"qty":250,"price":"$0.51064","currency":"USD"},{"qty":500,"price":"$0.43460","currency":"USD"},{"qty":1000,"price":"$0.34768","currency":"USD"},{"qty":2500,"price":"$0.31508","currency":"USD"},{"qty":5000,"price":"$0.30750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0c08f7770e1a42a40e1e2bd40fc7d708.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CD74HCT147E compatible with 74HC147?","answer":"The CD74HCT147E is the HCT (high-speed CMOS with TTL-compatible input thresholds) version of the 74HC147. Pinout and function are identical, but the HCT variant ensures direct compatibility with TTL logic levels on the inputs — useful when mixing 5 V TTL and CMOS families on the same board."},{"question":"What are the equivalent or replacement parts for CD74HCT147E?","answer":"The SN74LS348N is a functional alternative from the 74LS family, but it is an 8-line to 3-line encoder (1 x 8:3) with a narrower commercial temperature range (0°C to 70°C) and different output coding. For a direct 10:4 pin-compatible replacement, stick with the 74HCT147 or 74HC147 family in the same DIP-16 footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CD74HCT147E","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CD74HCT147E when reusing this data.
