This is a standard fine-pitch surface-mount footprint that routes cleanly on a two-layer board if the supply decoupling caps sit within 5 mm of the VCC/GND pins. The 0.65 mm pitch means the PCB land pattern follows the IPC-7351A SOT360-1 recommendation — no via-in-pad needed, but the solder paste stencil aperture should be 1:1 with the pad to avoid bridging on the inner rows. ## Supply voltage and timing margin The 2 V to 5.5 V supply range covers 3.3 V and 5 V logic rails without a separate level translator on the input side. At 5 V the propagation delay is 6.9 ns max into a 50 pF load — this sets the data setup time budget for the downstream latch or bus receiver. The 120 MHz clock frequency ceiling means the part handles 8-bit parallel data transfers at 120 million words per second. The positive-edge trigger synchronises the data capture to the rising clock edge, which simplifies timing closure in a single-clock-domain design. Quiescent current is 4 µA typical — negligible in a powered system, but relevant if the flip-flop sits in a battery-backed register bank where the supply stays on during sleep. ## Output drive and bus architecture The tri-state, non-inverted outputs source or sink 8 mA per pin. This is enough to drive a single TTL/CMOS load or a short (< 30 pF) bus trace directly. For heavily loaded backplanes or long parallel buses, a buffer after the output is recommended to keep the rise time within the next stage's input threshold window. With eight bits per element in a single package, the SN74AHC374PWR maps cleanly to an 8-bit data register or address latch. The tri-state control lets multiple devices share a common data bus without contention. ## Temperature grade and environment Rated for -40°C to +85°C ambient (TA), this is the industrial temperature range. The part is suitable for factory-floor controllers, telecom cabinets, and outdoor equipment enclosures that see diurnal temperature swings. Input capacitance is 4 pF per pin — the capacitive load on the driving stage is low, which helps maintain signal integrity on the clock and data lines at 120 MHz. ## Lifecycle and compliance The 74AHC series is a mature 5 V CMOS logic family. The SN74AHC374PWR is a standard catalogue part — no allocation risk or single-source dependency flagged in the supply chain data.","metaTitle":"SN74AHC374PWR Texas Instruments D-Type Flip-Flop, 120 MHz","metaDescription":"Texas Instruments SN74AHC374PWR D-type flip-flop, 8-bit, 120 MHz clock, 2V-5.5V supply, tri-state output, TSSOP-20.

Both are 20-TSSOP packages, but the SN74LVC574APWT has a different pin function — it is a D-type flip-flop with a different output polarity and a wider supply range (1.65 V to 3.6 V). The SN74AHC374PWR runs from 2 V to 5.5 V and has non-inverted outputs. The footprint is the same, but the electrical behaviour differs. Confirm the BOM's supply voltage and output polarity before substituting."},{"question":"What compliance documentation does Texas Instruments provide for SN74AHC374PWR?","answer":"Texas Instruments provides a ROHS3 compliance certificate for the SN74AHC374PWR.
