Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CMTDX' against current ON Semiconductor or Fairchild official documentation to confirm package type and tape-and-reel specifications. Confirm obsolescence status as the product may be discontinued. Ensure compatibility with existing PCB footprints and verify that the manufacturer has not replaced this part number with a newer generation equivalent without explicit notification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with independent control over two 8-bit nibbles. It is suitable for applications demanding low power consumption combined with high switching speeds. Consider the operating voltage range and ensure the system environment supports the specified three-state logic levels. Evaluate thermal requirements based on the expected load capacitance and switching frequency.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-speed BiCMOS logic devices. It is functionally similar to other 16-bit buffer drivers like the 74AC16244 but offers improved speed and lower power characteristics due to the ABT process. The device is typically packaged in a TSSOP or similar surface-mount format, distinguishing it from through-hole variants in the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes such as the 74ACT16244 or 74LCX16244 depending on voltage requirements. Verify if the legacy Fairchild designation maps to an ON Semiconductor part number. Ensure any replacement maintains the same nibble control architecture and three-state functionality.
