Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer marking on the component body matches Fairchild or its successor entities. Confirm the package type corresponds to the specified surface-mount configuration. Ensure the part number suffix aligns with the required tape-and-reel packaging format for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-drive current is required for bus lines. It serves as a suitable replacement for standard logic families requiring higher fan-out. Verify that the system operating voltage remains within the specified 4.5V to 5.5V range to ensure proper functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ABT logic family, which combines the speed of bipolar circuits with CMOS power efficiency. It is functionally similar to other octal bus drivers but offers superior drive strength. The specific CMSA suffix indicates the surface-mount package variant used in modern electronic assemblies.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives such as the 74ABT240 if inverting logic is acceptable. Verify electrical specifications against equivalent parts from other manufacturers to ensure compatibility with existing circuit designs.
