Overview

  • 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 LT1137A and LT1237
  • Flowthrough Architecture

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.

In Shutdown mode, all five receivers are kept alive and the supply current is 80µA. All RS232 outputs assume a high impedance state in Shutdown and with the power off.

The LTC1347 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120kbaud with a 2500pF, 3k Ω load. Both driver outputs and receiver inputs can be forced to ±25V without damage, and can survive multiple ±10kV ESD strikes.
