Product details

RS-232 transceiver for mixed-voltage serial links

The Maxim Integrated MAX3241EEWI+ is a full-duplex RS-232 transceiver in a 28-SOIC package, carrying three drivers and five receivers. It handles data rates up to 250 kbps and operates from a 3V to 5.5V supply, making it a direct fit for mixed 3.3V and 5V UART buses in industrial control, telecom infrastructure, and point-of-sale terminals. The 500 mV receiver hysteresis provides noise margin on long or electrically noisy cable runs — a practical advantage when the link stretches across a factory floor or through a switchgear cabinet.

Supply range and temperature grade — what they mean for the BOM

The 3V to 5.5V supply range covers 3.3V and 5V rails. The -40°C to 85°C rating suits industrial enclosures.

Production status: active, no LTB concern

The MAX3241EEWI+ has an active lifecycle status.

Package and footprint

Housed in a 28-SOIC wide-body package (7.50 mm width), the part is surface-mount. The 28-SOIC footprint is common across the family.

Frequently asked questions

What is the data rate of MAX3241EEWI+?

The MAX3241EEWI+ supports data rates up to 250 kbps, suitable for standard RS-232 UART links up to 230.4 kbps.

Can MAX3241EEWI+ replace MAX3241EAI?

Both parts are in the MAX3241 family and share the same 28-SOIC footprint and 3/5 driver/receiver count. The EWI+ variant is specified for the -40°C to 85°C industrial temperature range; verify that the EAI variant's temperature grade and supply range match your application before substituting.

Is MAX3241EEWI+ compatible with 3.3V systems?

Yes, the 3V to 5.5V supply range includes 3.3V, so the part operates directly on a 3.3V rail without additional level translation.
