The 1.65 V to 3.6 V supply range lets it bridge 1.8 V, 2.5 V, and 3.3 V logic domains without a level shifter — useful in mixed-voltage boards where a single logic family must talk to both a low-voltage MCU and a legacy 3.3 V peripheral. ## 5.2 ns propagation delay — timing budget for the bus At 3.3 V with a 50 pF load, the max propagation delay is 5.2 ns. That is the number to enter into your timing closure spreadsheet for the data-to-clock path. The 24 mA symmetric output drive (both high and low) keeps edge rates fast enough to meet setup times on downstream loads without extra buffering. Input capacitance is 5 pF, so fanout on a 3.3 V bus is manageable — figure 10 to 15 loads before the rise time degrades. The quiescent current sits at only 10 µA, so it adds negligible draw to a battery-backed or always-on rail.","metaTitle":"SN74LVC74AD Dual D-Type Flip-Flop, 150 MHz, 14-SOIC","metaDescription":"TI SN74LVC74AD dual positive-edge D-type flip-flop with set/reset. 150 MHz clock, 5.2 ns prop delay at 3.3 V, -40 to 125°C.
