The driver output stage of the LT1039A offers signifi-
cantly improved protection over older bipolar and CMOS
designs. In addition to current limiting, the driver output
can be externally forced to
±
30V with no damage or
excessive current flow.

The driver outputs utilize high impedance overvoltage
protection, eliminating the flow of fault currents into
supplies, as will happen with conventional diode clamp
configurations.

Older RS232 Drivers and Other CMOS Drivers
Placing the LT1039A 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.
