NEXPERIA 74LVC1G74 Positive Edge Triggered D-Type Flip-Flop

The NEXPERIA 74LVC1G74 is a single positive-edge triggered D-type flip-flop with complementary outputs, designed for high-speed digital applications. This versatile integrated circuit features individual data (D), clock (CP), set (active-low SD), and reset (active-low RD) inputs, along with complementary Q and active-low Q outputs for flexible logic control. Data at the D-input that meets the setup and hold time requirements during a LOW-to-HIGH clock transition is stored and appears at the Q output, making it ideal for data synchronisation and storage tasks.

A key advantage of this flip-flop is its wide supply voltage range from 1.65V to 5.5V, allowing it to function as a voltage translator in mixed 3.3V and 5V environments. Inputs can be driven directly from either 3.3V or 5V devices, simplifying system design. Schmitt-trigger action on all inputs makes the circuit highly tolerant of slower input rise and fall times, enhancing noise immunity and reliability in electrically noisy conditions.

The device incorporates advanced features for robust operation, including IOFF circuitry for partial power-down applications. This circuitry disables the output to prevent damaging backflow current when the device is powered down. Additional protections include overvoltage-tolerant inputs up to 5.5V and ESD protection, ensuring long-term durability. With its CMOS technology, it offers very low power consumption while maintaining a direct interface capability with TTL logic levels.

Housed in a compact VSSOP8 package, it is suitable for space-constrained PCB designs. Its excellent performance specifications, including a propagation delay of 6ns typical and operation up to 280MHz, make it a reliable choice for a wide range of digital systems from consumer electronics to industrial controls.
