Procurement Notes

Verify the specific suffix and revision level against the official Analog Devices datasheet to ensure compatibility with your design requirements. Confirm that the 20-SOIC package dimensions match your PCB footprint constraints. Check for any recent lifecycle status updates or recommended alternative part numbers from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a single-supply 5 V RS-232 transceiver is required for space-constrained designs. Ensure the application environment stays within the specified -40°C to +105°C operational limits. Consider the 20-pin package size relative to available board space. Verify that the CMOS input thresholds align with your microcontroller or logic family output levels.

Part Context

The AD230 belongs to the Analog Devices family of 5 V CMOS RS-232 drivers and receivers. It serves as a complete solution for serial communication, combining both transmitter and receiver functions in a single package. This series is widely used in applications needing reliable data transfer between computers and peripherals without requiring dual voltage supplies.
