MAX13223EEUP+

MAX13223EEUP+ is a 2Tx/2Rx RS-232 transceiver. MAX13223E is a +3.0V to +5.5V-powered EIA/TIA-232 and V.28 communications interface with fault protection on the RS-232 line interface. This allows shorts of the transmitter outputs and receiver inputs to voltages in the ±70V range without adversely affecting the MAX13223E. The MAX13223E achieves 1μA supply current using Maxim’s AutoShutdown™ feature. The MAX13223E automatically enters a low-power shutdown mode when the RS-232 cable is disconnected or the receivers are inactive. The device turns on again when a valid transition at any receiver input is sensed. A proprietary, high-efficiency, dual charge-pump power supply and a low-dropout transmitter combine to deliver true RS-232 performance from a single +3.0V to +5.5V supply. Typical applications include telematics equipment, base stations, utility meters, industrial equipment, telecom equipment and POS terminal equipment.

• Data rates of 250Kbps for one transmitter switching while maintaining RS-232 output levels
• Robust protection to withstand load dumps, miswiring, and connector failures
• Overvoltage current limiting
• Current protection at transmitter outputs
• Thermal Shutdown Protection
• Temperature range from -40°C to +85°C
• Available in 20-pin TSSOP package
