Flip Flops Procurement Notes

Verify the specific suffix 'ADT' corresponds to the TSSOP-20 package and tape-and-reel or tube packaging as defined in the official datasheet. Confirm that the operating voltage range and logic family compatibility match the target design requirements before procurement. Ensure the component meets all environmental compliance standards specified by the manufacturer.

Flip Flops Selection Notes

Select this component when an octal flip-flop with three-state outputs is required in a low-voltage CMOS environment. It is suitable for designs needing high-speed data latching with minimal power consumption. Consider the TSSOP-20 package constraints and ensure the system voltage aligns with the 2.0 V to 3.6 V operational range specified for the VHCT series.

Flip Flops Part Context

This part belongs to the MC74VHCT574A series, which represents an evolution in high-speed CMOS logic families. It provides improved switching speeds and lower power dissipation compared to earlier HCT or LVC variants. The device is widely used in digital systems where multiple bits of data need to be stored and controlled simultaneously via a common clock signal.

Flip Flops Replacement Considerations

Check for direct pin-compatible alternatives such as the MM74VHC574MTC or other VHCT series devices from onsemi. Verify that any substitute maintains the same 3.3 V logic level compatibility and three-state output functionality. Ensure the replacement package matches the TSSOP-20 form factor if board space is constrained.
