Procurement Notes

Verify the specific suffix 'D' against official Texas Instruments or Fairchild documentation to confirm tape-and-reel packaging status. Ensure the component matches the exact TSSOP-56 physical dimensions and pinout specifications required by the target design. Cross-reference the manufacturer source, as distribution sources may list varying origins for this part number.

Selection Notes

Select this component when designing systems requiring high-density parallel data transfer with low power consumption. The LCX series offers 5V tolerant inputs suitable for mixed-voltage environments. Consider the TSSOP-56 footprint constraints and thermal dissipation requirements associated with driving multiple lines simultaneously at high frequencies.
