Each flip-flop has independent Set (Preset) and Reset inputs, and the outputs are complementary — both Q and Q̅ are available. The negative-edge trigger means the data on the D input is transferred to the output on the falling edge of the clock, which is useful when the preceding stage's data settles before the clock goes low. ## Parametric fit for 12V and battery-backed automotive ECUs The 2V to 6V supply range covers both 3.3V and 5V nominal rails, plus the 2V margin near battery brown-out. Quiescent current is 2 µA typical — low enough for always-on wake-up circuits in body controllers or door modules where the flip-flop holds a latch state while the rest of the ECU sleeps. Clock frequency is 74 MHz, which is sufficient for most automotive serial-peripheral interfaces and sensor data pipelines running below 50 MHz. The propagation delay is 15 ns max at 6V with a 50 pF load — this sets the timing budget for the next stage: a 74 MHz clock period is 13.5 ns, so the delay eats into the hold margin at the receiver, especially at lower supply voltages where the delay increases. Operating temperature spans -40°C to 125°C ambient, the full automotive Grade 1 range. At 125°C junction, the input capacitance remains 5 pF, but the propagation delay and output rise times will be at the upper end of the datasheet limits — derate the clock frequency to around 60 MHz for reliable operation at the high end.","metaTitle":"SN74HCS72QDRQ1 Texas Instruments D-Type Flip-Flop, 74 MHz","metaDescription":"Texas Instruments SN74HCS72QDRQ1 dual D-type flip-flop, AEC-Q100 automotive grade, 74 MHz clock, -40 to 125°C, 14-SOIC.
