DESCRIPTION
The LTC1338 is a 5-driver/3-receiver RS232 transceiver with very low supply current. In the no load condition, the supply current is only 500µA. The charge pump only requires four 0.1µF capacitors.

FEATURES
■ Low Supply Current: 500µA
■ 0.2µA Supply Current in SHUTDOWN
■ 50µA Supply Current in RECEIVER ALIVE Mode
■ ESD Protection Over ±10kV
■ Operates from a Single 5V Supply
■ Uses Small Capacitors: 0.1µF
■ Operates to 120k Baud
■ 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
■ Flowthrough Architecture

APPLICATIONS
■ Battery-Powered Modems
■ Battery-Powered DCE
■ Notebook Computers
■ Palmtop Computers
