Low Supply Current: 500µA

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.
