MAX3250CAI+

MAX3250CAI+ is a 2 Tx/2 Rx, RS-232 transceiver. It is a 3.0V to 5.5V powered, ±50V isolated EIA/TIA-232 and V.28/V.24 communications interface with high data-rate capabilities. The MAX3250 is a dual die part that operates with up to ±50V difference between the RS-232 side and the logic side (ISOCOM to GND). This makes the device ideal for operation in noisy conditions with high common-mode voltages. This feature prevents damage to the device if RS-232 lines are inadvertently short-circuited to a +24V or ±48V power bus. The MAX3250 is powered by a single 3V to 5.5V supply on the logic side. Power is transferred from the logic side to the isolated side by ±100V external capacitors. Applications include industrial control, programmable logic controllers, point-of-sale equipment, PC-to-router connections, diagnostic ports, and telecom equipment.

• Isolation breaks ground loops due to high common mode voltages while maintaining data rate
• 250kbps guaranteed data rate, ±50V isolation
• Active-low FAULT output signals excessive isolated-side voltage
• Integration of isolation and RS-232 saves space
• Shutdown allows multiple interfaces (IrDA, RS-232, RS-485) to be connected to the same UART
• High-impedance transmitter and receiver outputs in shutdown
• Inductorless/transformerless design simplifies EMI compliance
• Low-cost replacement for opto-isolated transceivers
• 28 SSOP package
• Temperature range from 0°C to +70°C
