Each of the two elements stores one bit, and the complementary outputs (Q and Q-bar) give you both polarities without an external inverter. Clocked at up to 34 MHz with a propagation delay of 18 ns into a 50 pF load at 5 V, this part fits synchronous logic chains where the bus timing budget is tight but the environment stays indoors — the commercial temperature grade (0°C to 70°C) limits it to controlled ambient conditions like office equipment, test gear, or appliance control boards. ## Supply and drive — what the 5 V rail needs to deliver The part runs on a 4.5 V to 5.5 V supply, so a regulated 5 V rail is the natural home. Quiescent current sits at 4 mA — negligible in a board-level budget but worth noting if the 5 V rail is shared with a sensitive analog front end. Output drive is asymmetric: 8 mA source, 2 mA sink. That sink figure is the limiting number when driving a bus or LED; if your load demands more than 2 mA low-side, buffer it. The 18 ns propagation delay is specified at 5 V with a 50 pF load — derate upward if your trace capacitance or fan-out is higher. ## Lifecycle and sourcing — active, no LTB watch needed The SN74ALS74ANS carries an active lifecycle status and is ROHS3 compliant. For a production BOM that needs a 5 V dual flip-flop in a wide SOIC-14, this part is a stable line item — no near-term obsolescence risk.","metaTitle":"SN74ALS74ANS D-Type Flip-Flop, 34 MHz, 14-SOIC","metaDescription":"TI SN74ALS74ANS dual D-type flip-flop with set/reset, 34 MHz clock, 18 ns prop delay, 4.5-5.5 V, 14-SOIC.
