Working Principles

The SN74HC377DWRG4 is a flip-flop IC that stores and transfers data based on clock pulses. When the clock pulse input (CP) transitions from low to high, the data inputs (D1-D8) are latched and stored in their respective flip-flops. The stored data is then available at the corresponding output pins (Q1-Q8). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74HC377DWRG4 is commonly used in various digital systems where data storage and transfer are required. Some of its application fields include:

  1. Microcontrollers and Microprocessors
