Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '602' against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status as indicated in the product specification. Check for any recent PCN notices regarding manufacturing site changes or material updates before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with 3-State outputs is required for high-speed bus applications. Ensure the system voltage falls within the 4.5V to 5.5V range. Consider the 20-pin plastic SO package availability if surface mount assembly is preferred over through-hole options.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT logic family, known for high speed and low power consumption. It is functionally compatible with other 74ABT series devices but offers specific inversion characteristics. The 'D' suffix indicates a 20-pin plastic SO package, while '602' denotes the specific tape and reel packaging configuration.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-to-pin replacements within the 74ABT family such as the 74ABT240N or 74ABT240DB depending on package requirements. Verify that substitute parts meet the same electrical specifications for propagation delay and output drive current.
