J-K Type Flip-Flops

Robust interfacing between asynchronous and synchronous systems

Flip-flops are basic storage elements in digital electronics. By only allowing the output to change on an edge transition, flip-flops provide a robust interface between asynchronous and synchronous systems. With a choice of either positive or negative edge triggered options they provide added design flexibility.

Key features and benefits

  • Mixed 5 V and 3.3 V applications
  • Improved signal integrity with integrated termination resistors
  • High noise immunity
  • Flow through pin out for easy layout
  • Wide supply voltage range
  • Low propagation delay
  • Overvoltage tolerant input options
  • Integrated source termination resistor options
  • Bus hold options

Key applications

  • Frequency division
  • Controlled delays
  • Interface between asynchronous and synchronous systems
