APPLICATIO S I FOR ATIO
LTC4300A-1/LTC4300A-2
meeting rise- and fall-time specifications for one nanofarad
of capacitance, thus allowing much more interconnect
distance. In this situation, the differential ground voltage
between the two systems may limit the allowed distance,
because a valid logic low voltage with respect to the
ground at one end of the system may violate the allowed
V
end. In addition, the connection circuitry offset voltages
of the back-to-back LTC4300A-1s add together, directly
contributing to the same problem.
Systems with Disparate Supply Voltages
(LTC4300A-1)
In large 2-wire systems, the V
at various points in the system can differ by a few hundred
millivolts or more. This situation is well modelled by a
series resistor in the V

Redundancy (LTC4300A-2)
Systems requiring different supply voltages for the
backplane side and the card side can use the LTC4300A-2,
as shown in Figure 9. The pull-up resistors on the card side
connect from SDAOUT to SCLOUT to V
the backplane side connect from SDAIN and SCLIN to V
The LTC4300A-2 functions for voltages ranging from 2.7V
to 5.5V on both V

This application also provides power supply redundancy.
If the V
LTC4300A-2 disconnects the backplane from the card, so
that the backplane can continue to function. If the V
voltage falls below its UVLO threshold and the V
voltage remains active, ground the ACC pin to ensure
proper operation.
