Description
The FT1032 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 minimised.
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 FT1032 is the high impedance
output state when off or powered down.
For applications requiring dual or triple RS232 driver/
receiver devices, see the FT1180A (dual), FT1039A (triple)
or the FT1130A data sheets.
