Product details

Single D-type flip-flop with set and reset for automotive logic

The 140 MHz clock frequency supports high-speed data latching in CAN transceiver handshake or SPI bus isolation stages.

This part carries AEC-Q100 qualification, the automotive industry's stress-test standard for integrated circuits. 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

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.

Frequently asked questions

Is SN74LVC2G74QDCURQ1 AEC-Q100 qualified?

Yes, the SN74LVC2G74QDCURQ1 is part of the Automotive, AEC-Q100 series, meaning it has passed the automotive stress qualification tests for reliability in harsh environments.

Can SN74LVC2G74QDCURQ1 replace SN74LVC2G74DCUR?

Yes, the SN74LVC2G74QDCURQ1 is pin-compatible and functionally identical to the SN74LVC2G74DCUR. The key difference is the Q1 suffix adds AEC-Q100 qualification and the extended -40°C to 125°C temperature range, making it suitable for automotive environments where the commercial-grade DCUR is not rated.

What is the difference between SN74LVC2G74 and SN74LVC2G74Q1?

The SN74LVC2G74Q1 variant (which includes the QDCURQ1 order code) adds AEC-Q100 automotive qualification and a -40°C to 125°C operating temperature range. The base SN74LVC2G74 (without Q1) is a commercial/industrial-grade part with a narrower temperature range and no automotive stress testing.
