It belongs to the 74AHCT logic family, which is designed for 5V supply rails and offers TTL-compatible input thresholds. The part is AEC-Q100 qualified and rated over the full -40°C to 125°C automotive temperature range, making it suitable for engine control units, transmission controllers, and body electronics where a reliable flip-flop is needed for register, counter, or state-machine applications. Clock frequency reaches 140 MHz, and propagation delay is 8.8 ns at 5V with a 50 pF load — fast enough for most automotive serial interfaces and synchronous logic chains. ## 140 MHz clock — what it buys you The 140 MHz maximum clock frequency is the practical ceiling for cascading these flip-flops in a synchronous design. With an 8.8 ns propagation delay at 5V, 50 pF, the part can clock data through a pipeline at rates that comfortably exceed typical automotive SPI or CAN controller speeds. The 2 µA quiescent current is negligible for a 5V logic device, so power draw is dominated by dynamic switching at the output load. ## Package and footprint Housed in a 14-TSSOP package (4.40 mm body width), the SN74AHCT74QPWRQ1 is a surface-mount part. The supplier device package is 14-TSSOP, and the part is supplied on Tape & Reel or Cut Tape. ## Lifecycle and sourcing It is ROHS3 compliant and carries no last-time-buy or end-of-life notice.","metaTitle":"SN74AHCT74QPWRQ1 D-Type Flip-Flop, AEC-Q100, 140 MHz","metaDescription":"TI SN74AHCT74QPWRQ1 dual D-type flip-flop with set/reset, 140 MHz clock, 8.8 ns propagation delay.
