5V Low Power RS232

5-Driver/3-Receiver Transceiver

DESCRIPTIO

EATURE

■

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

The LTC1338 is a 5-driver/3-receiver RS232 trans-

ceiver with very low supply current. In the no load

condition, thesupplycurrentisonly500µA. Thecharge

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.
