Quad Low Power

Line Driver

FEATURES

DESCRIPTIO

The LT^®1032 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

fullyprotectedfromexternallyappliedvoltagesof±30Vby

bothcurrentandthermallimiting. Sincetheoutputswings

to within 200mV of the positive supply and 600mV of the

negative supply, power supply needs are minimized.

■

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

■

Also included is a strobe pin to force all outputs low

independent of input or shutdown conditions. Further,

slew rate can be adjusted with a resistor connected to the

supply.

APPLICATIO S

■

RS232

■

Power Supply Inverter

A major advantage of the LT1032 is the high impedance

output state when off or powered down.

■

Micropower Interface

Level Translator
