Product Details 74HC74D-Q100,118 is a dual positive-edge-triggered D-type flip-flop from the Nexperia 74HC logic family. The device integrates two independent D-type flip-flop elements, providing a compact solution for storing and synchronizing digital data in sequential logic circuits.Each flip-flop has an individual data input, clock input, set input and reset input. Data present at the D input is transferred to the corresponding output on the low-to-high transition of the clock signal when the required setup and hold conditions are satisfied. This positive-edge-triggered architecture makes the device suitable for synchronous digital systems where data needs to be captured at defined clock events.The device provides complementary Q and inverted Q outputs for each flip-flop. These outputs allow the stored logic state and its complementary signal to be used directly by subsequent logic stages, reducing the need for additional inverter circuits in many digital designs.Independent set and reset inputs provide asynchronous control over each flip-flop. These functions can be used to establish a known logic state during system startup, reset sequences or other control conditions without waiting for a clock transition.74HC74D-Q100,118 operates from a 2V to 6V supply range and uses CMOS logic input levels. The device is designed for low power dissipation and high noise immunity, making it suitable for a wide range of digital control and interface circuits. Nexperia also incorporates Schmitt-trigger action on the clock inputs, improving tolerance to slower clock rise and fall times.The flip-flop inputs include clamp diodes, which can help designers interface signals through appropriate current-limiting resistors when input voltages exceed the supply voltage within the specified operating conditions. This provides additional flexibility for digital interface designs.The device can be used to implement data storage, timing control, synchronization, frequency division and sequential logic functions. By connecting the flip-flop outputs and clock signals appropriately, designers can create counters, registers, state-control circuits and other application-specific digital logic.74HC74D-Q100,118 is specifically qualified to the AEC-Q100 Grade 1 automotive standard. It is specified for operating temperatures from -40°C to +125°C, making it suitable for automotive electronic systems as well as industrial and general-purpose embedded equipment requiring automotive-qualified logic devices.The device is supplied in a 14-pin SOIC package, providing a compact surface-mount solution for two independent D-type flip-flop channels. The package integrates the required data, clock, set, reset and complementary output connections while maintaining a relatively small PCB footprint.Typical applications include automotive control electronics, digital timing circuits, data storage, sequential logic, frequency division, interface control and embedded digital systems. The dual-channel structure allows two independent storage functions to be implemented with a single logic IC.When designing with 74HC74D-Q100,118, engineers should verify the supply voltage, clock frequency, setup and hold timing, propagation delay, input levels, output loading and asynchronous set/reset requirements according to the specific circuit and the latest Nexperia documentation.
