• Industrial control systems requiring reliable serial communication
• Point-to-point or multi-drop networking interfaces
• Data acquisition equipment in harsh environments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation as requirements vary by region. Check moisture sensitivity level handling instructions prior to assembly. Ensure the QFN-EP-24 footprint matches the design layout. Validate that the 3 V to 5.5 V supply range aligns with system power rails.

Drivers, Receivers, Transceivers Selection Notes

Select this component when only transmitter functionality is required for RS-422 networks. Compare against transceiver options if receiver capability is also needed. Consider the 32 Mb/s speed limit against higher baud rate requirements. Evaluate the QFN-EP-24 thermal performance for dense PCB layouts. Verify compatibility with existing 3.3 V or 5 V logic families.
