The SN74AHC74MDREP: The 8 mA output drive per pin (both high and low) is enough to switch the inputs of downstream logic families without an external buffer at moderate fan-out. Quiescent current is just 2 µA, making it suitable for power-sensitive designs where the flip-flop sits idle most of the time.

Input capacitance is 2 pF per pin, a light load for the driving stage. The part is available in tape and reel or cut tape, matching both production and prototype volume needs.
