LT1780/LT1781

Low Power 5V RS232

Dual Driver/Receiver with

±15kV ESD Protection

DESCRIPTIO

EATURE

TheLT^®1780/LT1781aredualRS232driver/receiverpairs

with integral charge pump to generate RS232 voltage

levels from a single 5V supply. Using only 0.1µF external

capacitors, these circuits consume only 40mW of power,

and can operate to 120kbaud even while driving heavy

capacitiveloads. NewESDstructuresonthechipallowthe

LT1780/LT1781 to survive ±15kV air gap and ±8kV con-

tact ESD tests per IEC 1000-4-2, eliminating the need for

costly TransZorbs^®on the RS232 line pins. The LT1780/

LT1781 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.

Absolutely No Latch-up

The LT1780/LT1781 are direct upgrades to the LT1180A/

LT1181A,LT1280A/LT1281AandLT1381forapplications

which require the utmost ESD protection.
