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

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.

In SHUTDOWN mode, the supply current is further reduced to 0.2µA. In RECEIVER ALIVE mode, all three receivers are kept alive and the supply current is 50µA. All RS232 outputs assume a high impedance state in SHUTDOWN and with the power off.

The LTC1338 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120k baud with a 2500pF, 3kΩ load. Both driver outputs and receiver inputs can be forced to ±25V without damage, and can survive multiple ±10kV ESD strikes.
