FEATURES  
DESCRIPTIO  
The LTC®1334 is a low power CMOS bidirectional trans-  
ceiver featuring two reconfigurable interface ports. It can  
be configured as two RS485 differential ports, as two dual  
RS232 single-ended ports or as one RS485 differential  
port and one dual RS232 single-ended port. An onboard  
charge pump requires four 0.1µF capacitors to generate  
boostedpositiveandnegativesupplies,allowingtheRS232  
drivers to meet the RS232 ±5V output swing requirement  
with only a single 5V supply. A shutdown mode reduces  
the ICC supply current to 10µA.

Shutdown or with Power Off  
Thermal Shutdown Protection  
Receiver Inputs Can Withstand ±25V  
The RS232 transceivers are in full compliance with RS232  
specifications. The RS485 transceivers are in full compli-  
ance with RS485 and RS422 specifications. All interface  
drivers feature short-circuit and thermal shutdown pro-  
tection. An enable pin allows RS485 driver outputs to be  
forced into high impedance, which is maintained even  
when the outputs are forced beyond supply rails or power  
is off. Both driver outputs and receiver inputs feature  
±10kV ESD protection. A loopback mode allows the driver  
outputs to be connected back to the receiver inputs for  
diagnostic self-test.
