The driver output stage of the LT1080 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. Some
drivers have diodes connected between the outputs and
the supplies, so externally applied voltages can cause
excessive supply voltage to develop.
Placing the LT1080 in the SHUTDOWN mode (Pin 18 low)
puts both the driver and receiver outputs in a high imped-
ance state. This allows data line sharing and transceiver
applications.
The SHUTDOWN mode also drops input supply current
(VCC; Pin 17) to zero for power-conscious systems.
