Description
The TPT29548A is a 1:8 bidirectional translating I2C
switch. The SCL/SDA upstream pair fans out to eight
downstream channels. Any single SCn/SDn channel
or combination of channels can be selected,
determined by the programmable control register.
If one of the downstream I2C buses is stuck in a low
state, then an active-low reset (?RESET ?????????) input helps
the TPT29548A to recover. Pulling ?RESET ????????? low resets
the I2C state machine and causes all the channels to
be deselected, as does the internal power-on reset
function.
The pass gates of the switches are constructed such
that the VCC terminal can be used to limit the
maximum high voltage, which will be passed by the
TPT29548A. This allows the use of different bus
voltages on each pair, so that 2.5 V, or 3.3 V parts
can communicate with 5 V parts, without any
additional protection. External pull-up resistors pull
the bus up to the desired voltage level for each
channel. All I/O terminals are 5.5 V tolerant.
TPT29548A is available in TSSOP24 and QFN24L
package, and is characterized from ?40°C to +85°C
