MAX13223E RS232 transceiver

Maxim Semiconductor introduces new  RS232 transceiver . The MAX13223E is like other RS232 communication chip ( Max232 ) but the difference is the ±70V Fault-Protection .

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.  The 70V protection of the MAX13223E  allows shorts of the

transmitter outputs and receiver inputs to voltages in the ±70V range without affecting the MAX13223E.

When the RS-232 cable is disconnected the MAX13223E automatically enters a low-power shutdown mode and is turned on again when a valid transition at any receiver input is sensed.

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.

MAX13223E  RS232 transceiver is ideal for telecommunication equipments , automotive telematics equipment , base stations , utility meters , POS terminal equipment .

Other features of the MAX13223E  transceiver are : ±70V Fault Protection , +3.0V to +5.5V Supply Voltage ,  Overvoltage Current Limiting , Current Protection at Transmitter Outputs ,  AutoShutdown ,  250kbps (Max) Data Rate , Low Current Consumption in Shutdown 1μA (typ) , Thermal Shutdown Protection ,  ±8kV IEC 61000-4-2 Contact-Discharge Method .
