What this dual flip-flop brings to the board
The SN74AC74DR is a dual D-type flip-flop from TI's 74AC family, packing two independent positive-edge-triggered flip-flops with individual set and reset pins into a 14-SOIC package. Each flip-flop stores one bit and provides complementary Q and Q̅ outputs. The 160 MHz clock frequency and 6 ns propagation delay at 5V, 50pF make it a solid choice for high-speed data latching, clock dividers, and state machines in industrial control, telecom, and instrumentation where you need to keep timing margins tight.
The 2V to 6V supply range covers both 3.3V and 5V logic rails without a level translator, which simplifies mixed-voltage designs. Quiescent current sits at 2 µA, so this part won't eat into your standby budget. Input capacitance is 3 pF, light enough that a 160 MHz clock source won't see a heavy load.
The 14-SOIC (0.154", 3.90 mm width) body is a standard surface-mount footprint. Board layout matches the common SOIC-14 land pattern; no surprises for the PCB designer.
No need to derate for cold starts or summer heat inside a panel.
TI lists the SN74AC74DR as Active.
