Part Number: P82B715 can I use different pullup (5v sx) and VCC and LX (12v) for P82B715 I2C extenders? What Lx pullup do I need? I was going to use 1k for sx.

Hi Team,
We plan to build a system as showing in the picture, could you help review does this work or there is any problem, thank you very much…
Part Number: P82B715 Other Parts Discussed in Thread: LM1117 Hello,
There seems to be conflicting information on the TI website regarding I2C pullup resistors.
I2C Bus Pullup Resistor Calculation (2015) https://www.ti.com/lit/an/slva689/slva689.pdf…
Part Number: P82B715 1)In the datasheet it is mentioned as "If P82B715 devices are to be permanently connected into a system, the circuit may be configured with only one pullup resistor on the buffered bus"
It means we can provide pull up to lx and…
Part Number: P82B715 Hi,
We need to transfer I2C data less than 1Mbps for up to 5 meters using RJ11 cable is it recommended,
or only Belden cable 9842 similar RS485 with 2 pair twisted cable is mandatory for Power, SDA, SCL, Gnd

Hi,
I'm trying to read the inclination angle from my inclinometer, my main board(MCU) is connected to accelerometer (located on daughter board) via a 1 meter (4 core shielded) cable, as…
Part Number: P82B715 Other Parts Discussed in Thread: TCA9517A , P82B96 Hi Team,
Please help to review the schematics whether is ok and whether the pull-up resistors value are ok.
The concept is to allow 3.3V MCU I2C Master to communicate with a 3…
Part Number: P82B715 Hello.,
BUFFER IC VCC 3.3V
and MASTER is 3V, I2C PULL-HIGH was 3V also
then through 715 to SLAVE side PULL-HIGH all 3.3V
is there any concern for the application, thanks
Part Number: P82B715 hi,
Please help to verify the P82B715DR design below, to buffer external long signal Lx, Ly (5V) to Sx, Sy (3.3V), for use on this board. We have multiple I2C end devices. Will this work?
Best regards, Felix
Part Number: P82B715 Hi Team ,
Please review the attached schematic of I2C level translator.
Pull-up of value 10k has been added on I2C2_SDA in other section of circuit .
Each I2C bus has 4 slaves --- ( 2 before buffer and 2 after buffer…
