Flip Flops Procurement Notes

Verify the package type matches the required footprint, specifically the SOIC-16 configuration. Confirm that the suffix 'SJ' corresponds to the correct tape and reel or tube packaging as specified by the manufacturer's ordering information. Ensure the operating temperature range meets the application requirements before finalizing procurement.

Flip Flops Selection Notes

Select this component when a hex D-flip-flop with asynchronous reset is required for bus-based architectures. Consider the voltage compatibility between the 2.0V to 6.0V operating range and the system power supply. Evaluate propagation delay specifications against the maximum clock frequency requirements of the target digital circuit design.

Flip Flops Part Context

This part belongs to the Fairchild Semiconductor 74HC series of high-speed CMOS logic devices. It provides functionality similar to other hex D-flip-flops but includes specific output drive characteristics and noise immunity features typical of the HC family. The device is designed for general-purpose digital logic applications requiring reliable state storage and transfer.

Flip Flops Replacement Considerations

Equivalent parts include the SN74HC174 from Texas Instruments or the MC74HC174 from ON Semiconductor. Verify pinout compatibility and electrical specifications such as propagation delay and output current capabilities before substitution.
