For a BOM line that needs a standard 74HC priority encoder, this is not a shortage-risk part in normal market conditions. The 74HC family is mature and widely produced, so allocation pressure is rare unless a broader logic shortage hits the industry.","metaTitle":"CD74HC147M Priority Encoder, 1 x 10:4, 16-SOIC","metaDescription":"CD74HC147M 74HC priority encoder, 1 x 10:4 circuit, 2V-6V supply, -55°C to 125°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Priority Encoder","Series":"74HC","Circuit":"1 x 10:4","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 6V","Independent Circuits":"1","Operating Temperature":"-55°C ~ 125°C","Voltage Supply Source":"Single Supply","Supplier Device Package":"16-SOIC","Current - Output High, Low":"5.2mA, 5.2mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.20000","currency":"USD"},{"qty":10,"price":"$1.06900","currency":"USD"},{"qty":25,"price":"$1.01520","currency":"USD"},{"qty":100,"price":"$0.83380","currency":"USD"},{"qty":250,"price":"$0.77940","currency":"USD"},{"qty":500,"price":"$0.68878","currency":"USD"},{"qty":1000,"price":"$0.54378","currency":"USD"},{"qty":2500,"price":"$0.51300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0c08f7770e1a42a40e1e2bd40fc7d708.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to CD74HC147M?","answer":"The SN74LS348N is a through-hole priority encoder from the 74LS family, but it uses a 1 x 8:3 circuit (eight inputs, three outputs) compared to the CD74HC147M's 1 x 10:4 configuration, and its operating temperature is 0°C to 70°C commercial range only. The DS90CP22MT/NOPB is a crosspoint switch, not a priority encoder — it is not a functional substitute. For a pin-compatible 74HC priority encoder, the CD74HC147M is the standard choice; no exact second-source alternate is recorded, but any 74HC147 in 16-SOIC from another qualified manufacturer would be a drop-in."},{"question":"What is CD74HC147M used for?","answer":"The CD74HC147M is a priority encoder that converts nine active-low input signals into a four-line BCD output.
