Product details

RS-232 link for extreme-temperature serial ports

Noise margin and supply flexibility

Receiver hysteresis is specified at 500 mV, which gives the serial link margin against ground shifts and crosstalk on long cable runs — a practical advantage in factory-floor or vehicle harness installations. The single-supply range from 3V to 5.5V means the transceiver can run off a 3.3V logic rail or a 5V legacy bus without a separate RS-232 charge-pump supply, reducing BOM count.

Active production, ROHS3, and sourcing posture

For BOM planning: the part is sourced per RFQ against your quantity.

Frequently asked questions

Is MAX3223MDBREP a direct replacement for MAX3223ECPE?

The MAX3223ECPE is a different package (16-PDIP) and temperature grade. The MAX3223MDBREP is a 20-SSOP surface-mount part with the -55°C to 125°C range. They are not pin-compatible; verify the board footprint and environmental requirements before substituting.

What is the difference between MAX3223 and MAX3232?

The MAX3223 is a 2-driver/2-receiver full-duplex transceiver. The MAX3232 is also a 2/2 device but typically operates at a lower data rate (250 kbps vs 250 kbps — same nominal rate) and may have different receiver hysteresis or supply range. Check the respective datasheets for exact parametric differences.

Is MAX3223MDBREP RoHS compliant?

Yes, it is listed as ROHS3 Compliant.
