APPLICATIONS
LTC1545
The internal pull-up current sources will ensure a binary 1
when a pin is left unconnected and that the LTC1543/
LTC1545 and the LTC1344A enter the no-cable mode
when the cable is removed. In the no-cable mode the
LTC1543/LTC1545 supply current drops to less than
200 A and all LTC1543/LTC1545 driver outputs and
LTC1344A resistive terminations are forced into a high
impedance state.

The mode selection may also be accomplished by using
jumpers to connect the mode pins to ground or V
Cable Termination
Traditional implementations have included switching
resistors with expensive relays, or required the user to
change termination modules every time the interface
standard has changed. Custom cables have been used
