Technical details

Dual D-type flip-flop with set and reset — 110 MHz, full military temp

The complementary outputs (Q and Q̅) give you both polarities without an external inverter. Clocked at 110 MHz, this part sits in the 74AC family — the advanced CMOS logic that balances speed with the wide supply tolerance of 1.5V to 5.5V. Key characteristics: 10 pF input capacitance keeps the clock-line loading light; 4 µA quiescent current means it adds negligible draw to the supply rail; 24 mA sink and source drive handles standard logic fan-out to multiple loads without buffering. Propagation delay is 10 ns at 5V with a 50 pF load, which gives you a clean timing budget for 110 MHz operation.

The CD74AC74M clocks at 110 MHz. Max propagation delay is 10 ns at 5V with 50 pF load.

ROHS3 compliant, so it passes European and global RoHS requirements without exemption paperwork.
