FEATURES  
DESCRIPTIO  
The LT®1039 is a triple RS232 driver/receiver that in-  
cludes shutdown. Each receiver will accept up to ±30V  
input and can drive either TTL or CMOS logic. The RS232  
driversacceptTTLlogicinputsandoutputRS232voltage  
levels. The outputs are fully protected against overload  
and can be shorted to ground or up to ±30V without  
damage to the drivers. Additionally, when the system is  
shut down or power is off, the outputs are in a high  
impedance state allowing data line sharing. Bipolar cir-  
cuitry makes this driver/receiver exceptionally rugged  
against overloads or ESD damage.  
Operates from ±5V to ±15V Supplies

APPLICATIO S  
For applications requiring operation from a single 5V  
supply, see the LT1080A/LT1081A, LT1180A/LT1181A  
and LT1130A data sheets. For applications requiring  
15kV ESD, see the LT1039A.
