LT1180ACSW

The LT?
1180A/LT1181A are dual RS232 driver/receiver
pairs with integral charge pump to generate RS232 voltage 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 0.1?F external capacitors, these circuits consume only 40mW of power, and can operate to
120k baud even while driving heavy capacitive loads. New
ESD structures on the chip allow the LT1180A/LT1181A to
survive multiple ?10kV strikes, eliminating the need for
costly TransZorbs?
on the RS232 line pins. The LT1180A/
LT1181A 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.
