Part Number: P82B715
Hi Experts,
Good day! Could you help me to provide information for P82B715DR that is not found on the datasheet?
1. what is clock speed?
2. what is power dissipation?
Thank you in advance for your support.
Best regards…
Part Number: P82B715 Hi Experts,
Seeking your assistance on this query from Cx about P82B715 bus expander.
For this I have built a network (see schematic2.png), which unfortunately cannot be simplified further. A microcontroller sits with the first P82B715…
Part Number: P82B715 The datasheet says the pins are not connected internally, however sometimes NC means No Connect, so do not use at all. Just to make the ground plane better around the SDA/SCL lines coming in, I would like to ground both NC pins. Is…

Part Number: P82B715 Dear Team,
Kindly help me on this query,
I am using P82B715[TI] in my project. I am connecting two P82B715 in series connection over 30cm ribbon cable at 400Kbps Speed. On one end i have interfaced P82B715 with TMS320F28379DZWTS Microcontroller…
Part Number: P82B715 Other Parts Discussed in Thread: PCF8575 , Dar Sir/Madam,
May I check with you:
We have 2 IC connected together using I2C (P82B715 and PCF8575)
P82B715 is a I2C buffer, Vcc is 5V.
PCF8575 is an IO expander, Vcc is 3.3V
We connected…
Part Number: P82B715 Other Parts Discussed in Thread: P82B96 Hi sir,
We are considering the adoption of P82B715 in our system.
I am planning to place one on the main CPU side and one on the slave device side to connect the LXLY of P82B715.
At that time…
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 3.3V I2C…
Part Number: P82B715 Other Parts Discussed in Thread: LM1117 Hello,
There seems to be conflicting information on the TI website regarding I2C pullup resistors.

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
