The positive-edge trigger and complementary outputs make it a direct drop-in for breadboard or legacy through-hole designs that need a clean divide-by-two or data-register stage. Rated clock frequency hits 210 MHz, which is high for a through-hole DIP — the 14-DIP (0.300-inch, 7.62 mm pitch) footprint introduces parasitic inductance and capacitance that limit the practical toggle rate in a socketed prototype, but on a soldered board with short traces the 210 MHz ceiling is real. The max propagation delay is 11 ns at 5 V and 50 pF load, so the output settles within one 4.76 ns clock period at 210 MHz, leaving roughly 6 ns of setup-and-hold margin for the downstream stage. ## Supply rails and quiescent draw Quiescent current is just 2 µA, so the flip-flop's own draw is negligible in a mixed-signal board where the 5 V rail also powers an ADC or op-amp. The input capacitance is 3 pF per input, which keeps the AC loading on the driving gate low. Output drive capability is 24 mA source and 24 mA sink at the rated supply voltage. ## Industrial temperature grade and through-hole integration The 14-PDIP package (supplier device package 14-PDIP) is the same 0.300-inch-wide DIP used since the 1970s, so existing PCB footprints and sockets accept it without a layout change. The tube packaging (50 per tube typical for 14-DIP) is standard for through-hole assembly lines that feed auto-insertion or hand-load stations.","metaTitle":"SN74ACT74N Texas Instruments D-Type Flip-Flop, 210 MHz","metaDescription":"SN74ACT74N dual D-type flip-flop with set/reset, 210 MHz clock, 11ns propagation delay at 5V, 50pF.
