It captures data on the positive edge of the clock and presents it through tri-state, non-inverted outputs — standard fare for register, latch, and bus-interface applications in industrial control, telecom, and test equipment where the bus needs to be isolated when the flip-flop is not selected. The 175 MHz clock frequency gives you a solid timing budget for 50-100 MHz bus cycles without worrying about hold-time violations on the backplane. The 2V to 5.5V supply range means it sits comfortably on a 3.3V or 5V rail — no level translator needed between this part and the rest of the 74LV or LVC logic on the board. The 20-SOIC package is a common footprint for 8-bit registers; the 0.209\" body width fits standard SOIC-20 land patterns. The -40°C to 85°C industrial temperature grade covers the thermal envelope for factory-floor PLCs, outdoor base-station controllers, and HVAC panels. ## 175 MHz clock — what it buys you in timing margin At 175 MHz the part can handle a 5.7 ns clock period. With a max propagation delay of 10.6 ns at 5V and 50 pF load, you are not running this at the clock limit in a synchronous bus — the propagation delay is the gating factor, not the toggle rate. What 175 MHz tells you is the flip-flop's internal setup/hold window is tight enough that it will not be the slow link in a 50 MHz data path. The real number to check is the 10.6 ns prop delay against your worst-case clock-to-Q timing budget. The 16 mA source/sink drive is enough to drive a 50 pF bus trace or a handful of CMOS inputs on the same backplane. If you are driving a longer trace or a heavier load, budget for a buffer or use the 74LVTH family with higher drive. ## Lifecycle — active, no end-of-life watch needed Texas Instruments lists the SN74LV574ANSR as Active with ROHS3 compliance. No NRND flag, no last-time-buy notice on the horizon. For a production BOM this means you can qualify it for new designs without planning a second-source migration. The 74LV series is a mature logic family, so the risk of a sudden EOL is low — TI typically gives 12-18 months notice on logic-family phase-outs.","metaTitle":"SN74LV574ANSR D-Type Flip-Flop, 175 MHz, 2V-5.5V, 20-SOIC","metaDescription":"TI SN74LV574ANSR 8-bit D-type flip-flop with tri-state outputs. 175 MHz clock, 2V-5.5V supply, -40°C to 85°C.

Functionally it is the same 8-bit D-type flip-flop with tri-state outputs as the generic 74LV574. The 'SN' prefix is TI's standard logic marking; the 'NS' suffix indicates the SOIC wide-body package.
