Dual D-type flip-flop with set and reset — 110 MHz, full military temp
The Texas Instruments CD74AC74M is a dual positive-edge-triggered D-type flip-flop with individual set (preset) and reset inputs, each element storing one bit. 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. Rated across the full military temperature range of -55°C to 125°C, the CD74AC74M is suited for avionics, satellite bus interfaces, downhole instrumentation, and any environment where the board sees extreme thermal cycling. The 14-SOIC (3.90 mm width) surface-mount package keeps the footprint compact for dense PCB layouts. 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.
110 MHz clock — what it means for your timing closure
The CD74AC74M clocks at 110 MHz. Max propagation delay is 10 ns at 5V with 50 pF load.
