DESCRIPTION
The LTC1347 is a 3-driver/5-receiver RS232 transceiver with very low supply current. In the no load condition, the supply current is only 300µA. The charge pump only requires four 0.1µF capacitors.

FEATURES
■ Low Supply Current: 300µA
■ Five Receivers Kept Alive in Shutdown
■ ESD Protection Over ±10kV
■ Operates from a Single 5V Supply
■ Uses Small Capacitors: 0.1µF
■ Operates to 120kBaud
■ Three-State Outputs Are High Impedance When Off
■ Output Overvoltage Does Not Force Current Back into Supplies
■ RS232 I/O Lines Can Be Forced to ±25V Without Damage
■ Pin Compatible with LT1137 and LT1237
■ Flowthrough Architecture

APPLICATIONS
■ Notebook Computers
■ Palmtop Computers
