Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EWI+' against the manufacturer's official ordering information to confirm the extended temperature range (-40°C to +85°C) and surface-mount SO package configuration. Ensure that the component source provides valid RoHS compliance documentation as indicated by the '+' suffix. Cross-reference the part number with the latest datasheet revision to confirm availability status and any potential obsolescence notices from Analog Devices or Maxim Integrated.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring EIA/TIA-562 compliance with low power consumption constraints. The integrated charge-pump eliminates the need for external negative voltage generation, reducing bill-of-materials complexity. Consider the keep-awake mode for applications requiring unidirectional communication while minimizing power usage. Verify that the system's UART logic levels are compatible with the CMOS input thresholds provided by the receiver section.
