Overview

Low Supply Current: 300µA
ESD Protection: Over ±10kV
1µA Supply Current in Shutdown
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
Pin Compatible with LT^®1137A and LT1237
Flowthrough Architecture

The LTC1337 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 and can supply up to 12mA of extra current to power external circuitry.

In Shutdown mode, the supply current is further reduced to 1µA. All RS232 outputs assume a high impedance state in Shutdown and with the power off.

The LTC1337 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120k baud with a 1000pF//3kΩ load. Both driver outputs and receiver inputs can be forced to ±25V without damage, and can survive multiple ±10kV ESD strikes.
