The LT
1381 is a dual RS232 driver/receiver pair with
integral charge pump to generate RS232 voltage levels
from a single 5V supply. The circuit features rugged
bipolar design to provide operating fault tolerance and
ESD protection unmatched by competing CMOS designs.
Using only 0.1
μ
F external capacitors, the circuit con-
sumes only 40mW of power and can operate to 120kbaud
even while driving heavy capacitive loads. New ESD struc-
tures on the chip allow the LT1381 to survive multiple
±
10kV strikes, eliminating the need for costly TransZorbs
on the RS232 line pins. Driver outputs are protected from
overload and can be shorted to ground or up to
±
25V
without damage. During power-off conditions, driver and
receiver outputs are in a high impedance state, allowing
line sharing.
