Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CSCX' against official Fairchild documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required voltage levels and load conditions before procurement. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed data transfer requires precise timing control and strong drive strength. The ABT technology offers superior performance compared to standard TTL or CMOS families. Consider the 64mA sink and 32mA source currents for driving heavy capacitive loads or terminated transmission lines effectively.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the ABT (Advanced BiCMOS Technology) family, which combines the speed of bipolar transistors with the low power consumption of CMOS. It serves as a successor to older AC and AS families, offering improved noise immunity and higher drive currents while maintaining pin compatibility with legacy designs in many configurations.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74ABT244 series for non-inverting applications. Verify that replacement parts maintain the same 3-state functionality and output drive characteristics. Check for equivalent package dimensions if physical footprint constraints exist.
