Description

The MC74HC73N is a dual JK flip-flop with clear. This device consists of two independent JK flip-flops, each with individual J, K, Clock, and Clear inputs. It is commonly used for building counters, shift registers, and control logic circuits where bistable elements are needed.

Applications

  • Counters
  • Shift registers
  • Control logic circuits
  • Frequency dividers
  • Storage registers
  • Data synchronization

Features

  • High Speed Operation: fMAX = 50 MHz (typ) at VCC = 5V
  • Low Power Dissipation: ICC = 4 μA (max) at TA = 25°C
  • High Noise Immunity: VNIH = VNIL = 30 % VCC
  • Operating Voltage Range: 2V to 6V
  • Dual JK Flip-Flop
  • Individual J, K, Clock, and Clear Inputs
  • Negative-Edge Triggered Clock

Benefits

  • High-speed operation suitable for demanding applications.
  • Low power consumption for energy-efficient designs.
  • Reliable performance in noisy environments.
  • Flexible control with individual J, K, Clock, and Clear inputs.
  • Versatile building block for digital systems.
  • Cost-effective solution for bistable element requirements.

The MC74HC73N consists of two independent JK flip-flops that change state based on the J and K inputs and the negative-going edge of the clock signal. The clear input allows for asynchronous clearing of the flip-flop. The device operates from a supply voltage of 2V to 6V and is compatible with standard TTL logic levels. It is commonly available in a through-hole DIP package.
