It clocks at 70 MHz, runs from 2V to 6V, and sinks or sources 7.8 mA per output. The wide supply range is the headline differentiator: it bridges 3.3 V and 5 V logic domains without a level translator, which is the main reason a designer picks 74HC over 74LS or 74F families. The -40°C to 85°C industrial temperature grade suits outdoor telecom, motor-drive control, and factory-automation backplanes — not just office equipment. ## 31 ns propagation delay — timing budget for the bus Max propagation delay is 31 ns at 6 V supply and 50 pF load. That figure sets the data-to-clock setup window the upstream device must meet. If the driving logic has a 10 ns output hold time, the 31 ns delay leaves comfortable margin; if the upstream part is slower, you may need to stretch the clock period or switch to a faster logic family like 74F (the 74F374SCX-NS, for example, clocks at 140 MHz with 8.5 ns delay). The 3 pF input capacitance keeps the bus load light, so a single gate driver can fan out to several flip-flops without signal degradation. ## Active, ROHS3, 20-TSSOP — sourcing posture TI lists the SN74HC374PWT as Active with ROHS3 compliance. The 20-TSSOP footprint (4.40 mm width) is a common surface-mount package for board-level glue logic; it shares the same land pattern as many other 20-pin TSSOP bus buffers, so a second-source swap is straightforward if supply tightens.","metaTitle":"SN74HC374PWT D-Type Flip-Flop, 70 MHz, 20-TSSOP","metaDescription":"TI SN74HC374PWT 74HC D-type flip-flop, 8-bit, tri-state non-inverted output, 70 MHz clock, 2V–6V supply, -40°C to 85°C, 20-TSSOP.

If the driving logic is 5 V TTL (e.g., 74LS or 74F), the HCT version guarantees a clean logic-high at 2.0 V input. The HC version requires the input to reach about 3.5 V at 5 V supply to guarantee a high, which is fine when the driver is another CMOS output."},{"question":"Can SN74HC374PWT be used in high-speed applications?","answer":"The 70 MHz clock rate and 31 ns propagation delay suit moderate-speed bus buffering and register applications — think microcontroller address/data latching at 20–50 MHz bus speeds. For faster pipelines (above 100 MHz), consider the 74F374SCX-NS which clocks at 140 MHz with 8.5 ns delay."},{"question":"Is SN74HC374PWT compatible with 5V logic?","answer":"Yes. The 2V–6V supply range includes 5 V operation. With a 5 V supply, the CMOS input thresholds are typically 3.5 V for a logic high and 1.5 V for a logic low, so it interfaces directly with 5 V CMOS outputs. For 5 V TTL outputs, the HCT variant is the safer choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HC374PWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HC374PWT when reusing this data.
