Dual D-type flip-flop for 5V automotive logic
It belongs to the 74AHCT logic family, which is designed for 5V supply rails and offers TTL-compatible input thresholds. 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.
