It operates across a 2V to 6V supply range, making it suitable for mixed 3.3V and 5V logic systems. The 70 MHz clock frequency supports moderate-speed data buffering, address latching, and register applications in industrial control, motor drives, and telecom equipment where the -40°C to 85°C industrial temperature range is required. ## 70 MHz clock and 15 ns propagation delay — timing budget considerations The 70 MHz maximum clock frequency sets the upper bound for data throughput in bus-register and pipeline stages. The propagation delay of 15 ns at 6V supply with a 50 pF load is the nominal figure to use when calculating setup-and-hold margins. At lower supply voltages, expect the delay to increase — the datasheet's derating curves (not reproduced here) show the typical trade-off. For a 3.3V system at 25°C, budget roughly 20-25 ns per the family characteristics. The 3 pF input capacitance is light enough that bus loading is usually not a concern unless driving a long backplane trace. ## Output drive: 7.8 mA source and sink Each output can source or sink 7.8 mA, which is typical for the 74HC family. This drives one or two standard LSTTL loads or a handful of CMOS inputs directly. For driving LEDs, optocouplers, or relay coils, add external buffers — the 7.8 mA limit is per pin, and the package's total current ceiling (not listed here) must also be respected. The tri-state control (Output Enable, active low per the 374 function table) lets multiple devices share a common data bus without contention. ## Active lifecycle — no end-of-life risk for new designs The SN74HC374DW carries an Active lifecycle status from Texas Instruments. It is ROHS3 compliant. For production BOMs that require a 74HC octal flip-flop in a 20-SOIC footprint, this part is a straightforward, low-risk choice with no near-term supply discontinuity. ## 20-SOIC package — footprint and layout notes The 20-SOIC body is 7.50 mm wide (0.295\") with a 1.27 mm pin pitch. This is the standard SOIC-20 wide-body footprint shared by many 74HC and 74HCT logic parts. The surface-mount package suits automated assembly. No exposed thermal pad — power dissipation is through the leads and the board copper. The quiescent current is just 8 µA, so self-heating is negligible even at high ambient temperatures.","metaTitle":"SN74HC374DW Octal D-Type Flip-Flop, 70 MHz, 20-SOIC","metaDescription":"TI SN74HC374DW octal D-type flip-flop with tri-state outputs, 70 MHz clock, 2V-6V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"D-Type","Series":"74HC","Package":"Tube","Function":"Standard","Output Type":"Tri-State, Non-Inverted","Trigger Type":"Positive Edge","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","Clock Frequency":"70 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 6V","Input Capacitance":"3 pF","Number of Elements":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-SOIC","Current - Quiescent (Iq)":"8 µA","Current - Output High, Low":"7.8mA, 7.8mA","Number of Bits per Element":"8","Max Propagation Delay @ V, Max CL":"15ns @ 6V, 50pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.32","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.32000","currency":"USD"},{"qty":10,"price":"$1.18200","currency":"USD"},{"qty":25,"price":"$1.12200","currency":"USD"},{"qty":100,"price":"$0.92160","currency":"USD"},{"qty":250,"price":"$0.86148","currency":"USD"},{"qty":500,"price":"$0.76130","currency":"USD"},{"qty":1000,"price":"$0.60102","currency":"USD"},{"qty":2500,"price":"$0.56700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/487556f8ff005aff64267f7169631c13.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can SN74HC374DW be used at 3.3V?","answer":"Yes. The SN74HC374DW operates over a 2V to 6V supply range, which includes 3.3V.
