Rated for -40°C to 85°C, this transceiver suits factory-floor serial links, PLC programming ports, and outdoor telecom gear that sees temperature swings. The part is listed as Active, so there is no last-time-buy pressure — it remains a safe choice for production BOMs. ROHS3 compliant.
The MAX3221EUE+ is sourced through independent distribution and quoted to order against an RFQ.
The MAX3221EUE+ supports a data rate of 250 kbps, which covers standard serial speeds up to 115200 baud with margin.
The SP3232 is a pin-compatible RS-232 transceiver in the same 16-TSSOP package, but verify the supply voltage and data rate match your application before substituting.
