MAX3250EAI+T

MAX3250 is a 3V to 5.5V powered, ±50V isolated EIA/TIA-232 and V.28/V.24 communications interface with high data-rate capabilities. This device is a dual die part that operates with upto ±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. It has two receivers (Rx) and two drivers (Tx) and is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels. The transceivers have a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a 3V to 5.5V supply with a dual charge pump. It is used in applications such as industrial control, programmable logic controller, point-of-sale equipment, PC-to-router connections, diagnostic ports, telecom equipment.

• FAULT output signals excessive isolated-side voltage
• Shutdown allows multiple interfaces (IrDA, RS-232, RS-485) to be connected to the same UART
• High-impedance transmitter and receiver
• Supply current in shutdown is 20µA typical at (TA = +25°C)
• Inductor less/transformer less design simplifies EMI compliance
