Functional Features

The SN74AHCT273DBR is a D-type positive-edge-triggered flip-flop with eight individual flip-flops integrated into a single IC package. It operates on a clock signal and stores the data present at its inputs when a positive edge is detected on the clock input. The flip-flops can be cleared to a low state using the clear input. The clock enable input allows for controlling the clocking of the flip-flops.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - Compact integration of multiple flip-flops - Easy control of clocking and clearing

Disadvantages: - Limited number of flip-flops in a single package - Not suitable for applications requiring a large number of flip-flops

Working Principles

The SN74AHCT273DBR operates based on the principles of positive-edge-triggered flip-flops. When a positive edge is detected on the clock input, the data present at the inputs is latched and stored in the flip-flops. The stored data remains unchanged until the next positive clock edge occurs. The clear input allows for resetting the flip-flops to a low state, and the clock enable input controls the clocking of the flip-flops.

Detailed Application Field Plans

The SN74AHCT273DBR is commonly used in various digital systems and applications, including but not limited to: - Register circuits - Data storage systems - Address decoding circuits - State machines - Control units
