1Mbps isolated RS232 — supply range and signal integrity
The MAX33250EELC+ is an isolated RS232 transceiver from Analog Devices, handling full-duplex communication at 1 Mbps — fast enough for industrial UART links where galvanic isolation is needed between the controller and the serial port. The 500 mV receiver hysteresis filters out noise on long cable runs — a practical margin for industrial environments where ground potential differences are common.
Fully ROHS3 compliant, with no exemptions on the restricted substances — it ships in tray packaging, suitable for pick-and-place assembly without a moisture-sensitive label bake cycle (verify MSL level from the latest ADI document).
