Additional Details

The TC74LCX273FK typically operates within a supply voltage range of 2.0V to 3.6V. It features a propagation delay in the nanosecond range, depending on the exact operating conditions and load capacitance. The device is available in surface-mount packages, making it suitable for modern PCB assembly techniques. The operating temperature range typically spans from -40°C to +85°C, allowing it to be used in a variety of environments. The input and output pins are designed to be compatible with other standard logic families, facilitating integration into existing systems. The clear input is an active-low input, meaning that a low signal on this pin will reset all the flip-flops regardless of the clock or data inputs.
