Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against Fairchild Semiconductor specifications. Confirm the package type matches the SC-88 or similar surface-mount designation associated with the CSCX suffix. Ensure the operating voltage range aligns with your system's 2.3V to 3.6V requirement before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed data transfer is required alongside significant current drive capabilities. The ABT series offers superior switching performance compared to standard CMOS logic. Consider the specific pinout and thermal characteristics of the surface-mount package for PCB layout optimization in dense designs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ABT (Advanced BiCMOS Technology) family, which bridges the gap between speed and power consumption. It serves as a direct replacement for older Schottky TTL devices in high-performance digital systems, offering improved noise immunity and faster transition times than standard AC or ACT logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the 74ABT244 from other manufacturers such as Texas Instruments or ON Semiconductor, provided they maintain identical pinouts and electrical characteristics. Verify that any alternative maintains the 64mA sink and 32mA source drive strengths.
