The propagation delay is 10 ns max at 5 V supply into a 50 pF load — this sets the timing margin for the data-to-clock setup window. At 250 MHz the clock period is 4 ns, so the 10 ns delay means this part is not a pipeline register at full speed; it is a bus-hold or control-register latch running at a divided clock rate, or a data-capture stage where the clock-to-Q delay is the limiting path. Output drive capability is 15 mA source, 12 mA sink — enough to drive a 50 pF load at 5 V without external buffers, but the edge rate into a higher capacitive bus will stretch the propagation delay beyond the 10 ns figure. The 200 µA quiescent current is the standby draw when the outputs are static; the dynamic current scales with the clock frequency and the number of outputs toggling. ## Supply rail and temperature grade The 10 ns propagation delay is specified at 5 V and 50 pF; derating at the low end of the supply range will add roughly 2–3 ns to the delay, so timing closure should be verified at 4.75 V and 85°C. ## Active lifecycle and compliance documentation The manufacturer provides standard compliance documentation including RoHS declaration of conformity and material composition data.","metaTitle":"CY74FCT2574ATSOC D-Type Flip-Flop, 250 MHz, 20-SOIC","metaDescription":"Active CY74FCT2574ATSOC D-type flip-flop, 250 MHz clock, 10 ns propagation delay, 20-SOIC surface mount.
