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
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.
