Single D-type flip-flop with set and reset for automotive logic
The Texas Instruments SN74LVC2G74QDCURQ1 is a single positive-edge-triggered D-type flip-flop with independent Set (Preset) and Reset inputs, part of the 74LVC family qualified to AEC-Q100 for automotive applications. It delivers complementary outputs (Q and Q̅) and operates across a wide supply range of 1.65 V to 5.5 V, making it a direct fit for mixed-voltage automotive ECUs, body controllers, and ADAS sensor interface boards where a single-bit latch with asynchronous initialization is needed. The 140 MHz clock frequency supports high-speed data latching in CAN transceiver handshake or SPI bus isolation stages.
AEC-Q100 qualification and temperature range
This part carries AEC-Q100 qualification, the automotive industry's stress-test standard for integrated circuits. Combined with an operating temperature range of -40°C to 125°C, it is rated for under-hood and engine-bay environments where ambient heat and thermal cycling are routine. The 74LVC logic family also provides 5 V tolerant inputs, so it can interface directly with legacy 5 V sensors or microcontrollers without external level shifters.
Output drive and propagation delay
Each output can source or sink 24 mA, enough to drive a standard logic input or a low-power LED indicator directly. Maximum propagation delay is 5.4 ns at 5 V with a 50 pF load, which keeps setup-and-hold margins tight in a 140 MHz clocked system. Quiescent current is 10 µA, so the flip-flop adds negligible standby draw in battery-backed automotive modules.
Sourcing and lifecycle
The SN74LVC2G74QDCURQ1 is listed as Active in production status and is ROHS3 compliant.
