Product Summary
The LT1381CS 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 0.1µF external capacitors, the LT1381CS consumes only 40mW of power and can operate to 120kbaud even while driving heavy capacitive loads. New ESD structures on the chip allow the LT1381CS 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. The applicaitons of the LT1381CS include Portable Computers, Battery-Powered Systems, Power Supply Generator, Terminals and Modems.
