Functional Features

  • High-speed operation: The SN74AUC32374GKER is designed for high-speed applications, with a maximum clock frequency of 500 MHz.
  • Low-power consumption: It operates at a low supply voltage range of 1.65 V to 3.6 V, making it suitable for battery-powered devices.
  • 3-state outputs: The flip-flop has 3-state outputs, allowing multiple devices to share a common bus without interference.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing. - Low-power consumption prolongs battery life in portable devices. - 3-state outputs facilitate bus sharing and reduce system complexity.

Disadvantages: - Limited number of bits (32) may not be sufficient for certain applications requiring larger data storage. - The package size (48-pin TSSOP) may require additional space on the PCB.

Working Principles

The SN74AUC32374GKER is a D-type flip-flop, which stores digital data using positive-edge-triggered clock inputs. When the clock signal transitions from low to high, the input data is latched and stored in the flip-flop's internal memory. The stored data can then be accessed through the output pins. The flip-flop also features an output enable pin, which allows the outputs to be disabled when necessary.
