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. ## Supply and drive — what the numbers mean for your BOM The 2V to 6V supply range covers both 3.3V and 5V logic rails without a level translator, which simplifies mixed-voltage designs. Each output can source or sink 24 mA — enough to drive a handful of downstream gates or a short PCB trace directly. 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. ## Package and footprint 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. The supplier device package is 14-SOIC, so the reel or cut-tape option (Tape & Reel or Cut Tape) lets you order exactly the quantity you need for prototyping or production. ## Temperature grade and environment Rated for -40°C to 85°C ambient, this flip-flop is comfortable in industrial enclosures, outdoor telecom cabinets, and factory-floor equipment where the temperature swings. No need to derate for cold starts or summer heat inside a panel. ## Lifecycle and compliance TI lists the SN74AC74DR as Active. It's ROHS3 compliant, so it passes the environmental requirements for EU and most global markets without an exemption hunt.","metaTitle":"SN74AC74DR D-Type Flip-Flop, 160 MHz, 14-SOIC, Active","metaDescription":"TI SN74AC74DR dual D-type flip-flop with set/reset, 160 MHz clock, 6 ns propagation delay at 5V, 50pF.
