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.
