APPLICATIONS INFORMATION
the LTC4312 can be cascaded with the LTC4303 and
LTC4307 if the LTC4312’s RTA turn-on voltage is set to be
0.8V (ACC low). The LTC4312 can be cascaded with the
LTC4301 and LTC4301L under all ACC settings as these
devices do not have RTAs. The LTC4312 can be cascaded
with the LTC4302, LTC4304, LTC4305 and LTC4306 if the
LTC4312’s RTAs are set to turn on at 0.8V (ACC low) or
under all ACC settings if the RTAs on the other bus buf-
fers are disabled. Finally, two LTC4312s can be cascaded
if their ACC pins are tied to the same state, HIGH, LOW
or open or if the ACC pin of one LTC4312 is tied high and
the other is left open.
Radial Telecommunications
Figure 6 shows the use of the LTC4312 in a radial telecom-
munications application. Two Shelf Managers are wired to
communicate with slave I2C devices for redundancy. Each
Shelf Manager can have as many LTC4312s as required
depending on the number of boards in the system and
the desired radial/star conguration. The ENABLE pins of
the LTC4312s inside only one Shelf Manager are asserted
high at any time. For simplicity, in Figure 6 only the SDA
pathway is shown. The SCL pathway is identical.

Path Is Shown for Simplicity
