Product details

What this RS-232 transceiver does on your serial port

The Maxim Integrated MAX3209ECUU+ is a full-duplex RS-232 transceiver with 6 drivers and 10 receivers in a 38-TSSOP package. It handles serial communication at up to 460 kbps, with 200 mV of receiver hysteresis. The supply rail is 10.8 V to 13.2 V. This is a commercial-temperature-grade device (0°C to 70°C).

Active production, no obsolescence worry

It is also ROHS3 compliant, which means no lead or restricted substances in the package — that keeps it usable for EU RoHS and similar regulatory markets without exemption paperwork. For new designs, the Active status means you can qualify it into the BOM without planning a second-source swap for the next few years.

Frequently asked questions

What is the maximum data rate of the MAX3209ECUU+?

The MAX3209ECUU+ supports a maximum data rate of 460 kbps. That covers standard RS-232 baud rates up to 115200 with margin, but it is not intended for multi-megabit serial protocols.

Is the MAX3209ECUU+ RoHS compliant?

Yes, the MAX3209ECUU+ is ROHS3 compliant, meaning it meets the EU RoHS directive without exemptions for lead or other restricted substances.
