LTC1347  
5V Low Power RS232  
3-Driver/5-Receiver Transceiver  
with 5 Receivers Active  
in Shutdown  
U
FEATURES  
DESCRIPTIO  
The LTC®1347 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.  
■
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  
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.  
■
Operates to 120kBaud  
■
Three-State Outputs Are High Impedance When Off  
■
Output Overvoltage Does Not Force Current Back  
The LTC1347 is fully compliant with all data rate and  
overvoltage RS232 specifications. The transceiver can  
operate up to 120kbaud 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.
