Modems

The LT

1180A/LT1181A 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

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.

The LT1181A is available in 16-pin DIP and SO packages.

The LT1180A is supplied in 18-pin DIP and SO packages

for applications which require shutdown.
