Functional Features

• CD74ACT280E is a 9-bit binary counter with a synchronous reset function.
• It can count up or down based on the input signals.
• The counter can be enabled or disabled using the Count Enable (CET) pin.
• The Master Reset (MR) pin resets the counter to its initial state.
• The clock input (CLK) determines the speed at which the counter increments or decrements.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Synchronous reset functionality - Wide operating voltage range

Disadvantages: - Limited number of bits (9-bit counter) - Not suitable for applications requiring higher bit counts

Working Principles

CD74ACT280E operates as a synchronous binary counter. It uses flip-flops to store and propagate the count value. The clock input triggers the flip-flops, causing them to change their state and increment or decrement the count based on the input signals. The counter can be reset to its initial state using the Master Reset pin.
