DESCRIPTIO  
EATURE  
S
F
The LT®1280A/LT1281A are dual RS232 driver/receiver  
pairs with integral charge pump to generate RS232 volt-  
age levels from a single 5V supply. These circuits feature  
rugged bipolar design to provide operating fault tolerance  
and ESD protection unmatched by competing CMOS  
designs. Using only 0.1µF external capacitors, these cir-  
cuits consume only 40mW of power, and can operate to  
120kbaud even while driving heavy capacitive loads. New  
ESDstructuresonthechipallowtheLT1280A/LT1281Ato  
survive multiple ±10kV strikes, eliminating the need for  
costly TransZorbs® on the RS232 line pins. The LT1280A/  
LT1281A are fully compliant with EIA RS232 standards.  
Driver outputs are protected from overload, and can be  
shorted to ground or up to ±30V without damage. During  
shutdown or power-off conditions, driver and receiver  
outputs are in a high impedance state, allowing line  
sharing.
