Overview

  • 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

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.

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.
