Functional Features

The SN74LS273DWG4 is a positive-edge-triggered flip-flop with a clear input. It has eight D-type flip-flops with individual clear inputs. The device operates on a supply voltage range of 4.75V to 5.25V and can handle high-speed digital signals up to 33 MHz. The clear input allows for synchronous clearing of all flip-flops, making it suitable for applications where simultaneous data storage is required.

Advantages and Disadvantages

Advantages: - Low-power consumption due to the use of Schottky TTL technology - High-speed operation up to 33 MHz - Individual clear inputs for each flip-flop allow for synchronous clearing

Disadvantages: - Limited operating voltage range (4.75V to 5.25V) - Propagation delay time of 15 ns may not be suitable for ultra-high-speed applications

Working Principles

The SN74LS273DWG4 operates based on positive-edge-triggered flip-flop principles. When a rising edge is detected on the clock input, the data present at the D inputs is transferred to the corresponding Q outputs. The clear input, when activated, clears all flip-flops simultaneously, setting their outputs to a low state.
