Frequently Asked Questions
What is the maximum clock frequency supported by the SN74LV74APWG4?
The SN74LV74APWG4 supports a maximum clock frequency of 45MHz at nominal supply voltage with a 50pF load capacitance. This performance level makes it appropriate for high-speed synchronous digital logic and clocked data path designs in embedded and communication systems.
What supply voltage does the SN74LV74APWG4 require?
The SN74LV74APWG4 operates from 2V to 5.5V, covering both 3.3V and 5V logic environments. Its LV-A family designation guarantees improved drive strength and propagation delay compared to the standard LV variant, making it a direct upgrade for performance-sensitive designs.
What package is used for the SN74LV74APWG4 and is it RoHS compliant?
This device is packaged in a 14-pin TSSOP (Thin Shrink Small Outline Package) which offers a compact footprint for high-density PCB assembly. The G4 suffix confirms it meets RoHS and REACH environmental compliance requirements with a lead-free, halogen-free construction.
What are common design applications for the SN74LV74APWG4?
The dual D-type flip-flop is widely used for clock domain crossing, data synchronization, divide-by-two frequency division, and building finite state machines. It is also employed in edge detection circuits, address latches in memory interfaces, and glitch-filtering stages in embedded digital designs.
Does the SN74LV74APWG4 include set and reset functionality?
Yes, the SN74LV74APWG4 provides independent active-low asynchronous preset (set) and clear (reset) inputs for each flip-flop element. These inputs allow the output state to be forced regardless of the clock signal, simplifying initialization and fault-recovery logic in digital designs.
