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.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: 3V applied to the strobe pin will force all outputs low. Strobe pin
input impedance is about 2k to ground. Leave open when not used.
Note 3: Response can be changed by connecting a resistor to the supply.
For supplies less than ±6V this current is disconnected when shut down.
Leave open when not used.
