GENERAL DESCRIPTION
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, highefficiency, 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. The MAX13223E 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. The MAX13223E operates from input voltages ranging from +3.0V to +5.5V and is available in a 20-pin, 6.5mm x 4.4mm, TSSOP package. The MAX13223E is specified over the -40°C to +85°C temperature range. o ±70V Fault Protection o +3.0V to +5.5V Supply Voltage o Overvoltage Current Limiting o Current Protection at Transmitter Outputs o AutoShutdown o 250kbps (Max) Data Rate o Low Current Consumption in Shutdown 1µA (typ) o Therm...
