That 16-PDIP footprint matches legacy sockets and prototyping boards; if your BOM is moving to SMT, the 74F174 family includes SOIC variants, but this exact order code is DIP only. The tube shipment is standard for through-hole logic — no reel, no carrier tape. ## Output drive and quiescent draw Output current ratings are 1 mA source, 20 mA sink per pin — enough to drive a TTL input or a low-current LED, but not a relay coil or bus transceiver without a buffer. The 45 mA quiescent supply current (Iq) is typical for a six-bit 74F register running at speed; it adds up across multiple devices on a 5V rail, so budget the total Iq for your power supply.","metaTitle":"SN74F174AN D-Type Flip-Flop, 140 MHz, 16-DIP","metaDescription":"TI SN74F174AN D-type flip-flop, 6-bit, master reset, 140 MHz clock, 10 ns propagation delay, 4.5-5.5V supply, 0-70°C, 16-DIP.","metaKeywords":null},"attributes":{"series":"74F","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"D-Type","Series":"74F","Package":"Tube","Function":"Master Reset","Output Type":"Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","Clock Frequency":"140 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"1","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-PDIP","Current - Quiescent (Iq)":"45 mA","Current - Output High, Low":"1mA, 20mA","Number of Bits per Element":"6","Max Propagation Delay @ V, Max CL":"10ns @ 5V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.76000","currency":"USD"},{"qty":10,"price":"$0.67200","currency":"USD"},{"qty":25,"price":"$0.63080","currency":"USD"},{"qty":100,"price":"$0.51490","currency":"USD"},{"qty":250,"price":"$0.47828","currency":"USD"},{"qty":500,"price":"$0.40704","currency":"USD"},{"qty":1000,"price":"$0.32563","currency":"USD"},{"qty":2500,"price":"$0.29510","currency":"USD"},{"qty":5000,"price":"$0.28800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/724f5a375b430d288f3d9c218f7029ee.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the SN74F174AN work with a 5V supply only?","answer":"Yes.
