RS-232 transceiver for multi-port serial links
The Maxim Integrated MAX3245EEUI+ is a full-duplex RS-232 transceiver packing three drivers and five receivers into a 28-TSSOP package. It handles 1 Mbps data rate across a 3V to 5.5V supply range, making it a fit for mixed-voltage serial ports in industrial controllers, point-of-sale terminals, and telecom line cards where multiple UART channels need level translation.
Driver/receiver count and supply flexibility
The 3V to 5.5V supply range lets it run from a 3.3V rail in battery-powered gear or a 5V rail in legacy backplanes, with no level shifter between the UART and the transceiver.
Rated from -40°C to 85°C, the MAX3245EEUI+ covers industrial environments — outdoor telecom cabinets, factory-floor serial gateways, and unheated enclosures. The 28-TSSOP package (4.40 mm width) suits dense PCB layouts where board space is tight.
Maxim lists the MAX3245EEUI+ as Active and ROHS3 compliant.
