DESCRIPTION
The LT1032 is a RS232 and RS423 line driver that operates over a ±5V to ±15V range on low supply current and can be shut down to zero supply current. Outputs are fully protected from externally applied voltages of ±30V by both current and thermal limiting. Since the output swings to within 200mV of the positive supply and 600mV of the negative supply, power supply needs are minimized.

FEATURES
■ Low Operating Voltage: ±5V to ±15V
■ 500µA Supply Current
■ Zero Supply Current when Shut Down
■ Outputs Can Be Driven ±30V
■ Thermal Limiting
■ Output “Open” when Off (Three-State)
■ 10mA Output Drive
■ Pinout Similar to 1488

APPLICATIONS
■ RS232
■ Power Supply Inverter
■ Micropower Interface
■ Level Translator
