MAX13223EEUP+T

MAX13223EEUP+T is a ±70V fault-protected, 2Tx/2Rx RS-232 transceiver. This allows shorts of the transmitter outputs and receiver inputs to voltages in the ±70V range without adversely affecting the device. It automatically enters a low-power shutdown mode when the RS-232 cable is disconnected or the receivers are inactive. This 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. It has two receivers and two drivers and is guaranteed to run at data rates of 250Kbps for one transmitter switching while maintaining RS-232 output levels. It is used in applications such as telematics equipment, base stations, utility meters, industrial equipment, telecom equipment, POS terminal equipment.

• ±70V fault protection, overvoltage current limiting
• Current protection at transmitter outputs, thermal shutdown protection
• AutoShutdown simplifies power savings, 1µA typical shutdown current
• Supply current is 8mA typical at (VCC = +3.0V to +5.5V, TA = -40°C to +85°C)
• Input leakage current is ±1µA maximum at (VCC = +3.0V to +5.5V, TA = -40°C to +85°C)
• Receiver input resistance is 250Kohm maximum at (VCC = V+ = V- = 0V)
• Maximum data rate is 250Kbps minimum at (RL = 3Kohm, CL = 1000pF, one transmitter switching)
• Receiver propagation delay is 0.3µs typ at (CL = 150pF, VCC = +3.0V to +5.5V, TA = -40°C to +85°C)
• Transmitter propagation delay is 0.8µs typical at (CL = 1nF, RL = 3Kohm, VCC = +3.0V to +5.5V)
• Operating temperature range from -40°C to +85°C, 20-pin TSSOP package
