Key Features

  • Wide Supply Voltage Range: Operates from 4.5 V to 5.5 V, making it suitable for a variety of applications.
  • Positive-Edge Trigger: The outputs Qn assume the state of their corresponding Dn inputs on the LOW-to-HIGH clock (CP) transition.
  • Master Reset: A LOW on the master reset (MR) input forces the outputs LOW, independent of clock and data inputs.
  • Low Power Dissipation: CMOS technology ensures low power consumption.
  • High Noise Immunity: Enhanced noise immunity due to the CMOS design.
  • Latch-Up Performance: Exceeds 100 mA per JESD 78 Class II Level B.
  • Compliance with JEDEC Standards: Meets JESD8C (2.7 V to 3.6 V) standards.
  • Input Clamp Diodes: Allows the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Applications

  • Digital Circuits: Suitable for use in various digital circuits requiring flip-flop functionality.
  • Sequential Logic Designs: Ideal for applications involving sequential logic, such as counters, shift registers, and memory elements.
  • Embedded Systems: Can be used in embedded systems that require low power and high reliability.
  • Automotive and Industrial Control Systems: Applicable in automotive and industrial control systems due to its wide operating temperature range and robust design.
