The LT

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

±30Vby

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.

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.

A major advantage of the LT1032 is the high impedance

output state when off or powered down.

For applications requiring dual or triple RS232 driver/

receiver devices, see the LT1180A (dual), LT1039A (triple)

or the LT1130A data sheets.
