Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CSCX' against official Fairchild documentation to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure compatibility with the 20-pin SOP footprint dimensions. Confirm RoHS compliance status matches current regulatory requirements for your region. Cross-reference the manufacturer part number with the latest datasheet revision to validate pinout integrity before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed octal buffering with flow-through architecture similar to the ABT244 but with opposite input/output placement. It is suitable for microprocessor output port interfaces where board density and layout ease are priorities. Consider the 64mA sink capability for driving heavy loads or multiple inputs on a shared bus structure without external buffering components.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ABT logic family, which combines advanced CMOS technology with Schottky diode clamping for high-speed performance. It serves as an octal variant within the broader 74-series logic ecosystem, specifically engineered for high-density digital systems. The component functions similarly to the ABT244 but offers a distinct pinout arrangement that facilitates different PCB layout strategies for complex digital interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The ABT244 is functionally similar but features a broadside pinout rather than flow-through. Verify pin compatibility if substituting directly into existing footprints. Other octal buffers like the 74AC541 offer comparable functionality but differ in speed and voltage specifications.
