APPLICATIONS INFORMATION
WU
U
The driver output stage of the LT1039 offers significantly
improved protection over older bipolar and CMOS de-
signs. In addition to current limiting, the driver output
can be externally forced to
±30V with no damage or
excessive current flow, and will not disrupt the supplies.
LT1039 Driver
Some drivers have diodes connected between the out-
puts and the supplies, so externally applied voltages can
cause excessive supply voltage to develop

Sharing a Transmitter Line
Placing the LT1039 in the shutdown mode (Pin 17 low)
puts both the driver and receiver outputs in a high imped-
ance state. This allows data line sharing and transceiver
applications.
