Functional Features

• The MC74HC273ADTR2G is a positive-edge triggered flip-flop, meaning it captures and stores data on the rising edge of the clock signal.
• It has eight individual flip-flops (D-type) that can store one bit each.
• The flip-flops can be cleared to a known state using the CLR (clear) input.
• The outputs (Q1-Q8) reflect the stored data when the clock signal rises.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - CMOS logic provides low power consumption. - Octal configuration enables storage of multiple bits in a single IC. - Positive-edge triggering ensures reliable data capture.

Disadvantages: - Limited number of flip-flops (8) may not be sufficient for complex applications. - Requires an external clock signal for proper operation.

Working Principles

The MC74HC273ADTR2G operates based on the principles of positive-edge triggered flip-flops. When the clock signal rises, the inputs (D0-D7) are captured and stored in their respective flip-flops. The stored data is then available at the outputs (Q1-Q8). The CLR input can be used to clear all flip-flops to a known state.
