Part Number: PCA9546A Hi.
First, some background.
I am developing a unit with four identical slots for plug-in modules. These modules will be identical insofar as the I2C devices on them and therefore have the same addresses. To manage this, I added…
Part Number: PCA9546A Other Parts Discussed in Thread: TCA9544A , TCA9546A , What is the difference between PCA9546 and TCA9544A? Which is recommended for an application which involves an MCU talking to 4 sensors over I2C with the same address?
How is the…
Part Number: PCA9546A Our application uses two FPGAs to simultaneously control this chip, with one main device and one backup device. If one device has an issue, the other can be backed up. However, in this application, there is a problem with the SCL…

Hi,
I want to use 4 IC I2C DAC LTC2616 using the same I2C of the microcontroller. In order to save power consumption I will place a power switch for each one VCC Power. This is the comment…

Hi
Can you help to review the following cirucit?
We find there is no ACK from slave device.
Part Number: PCA9546A HI,
I would like to confirm whether the PCA9546A can be used in 1.8V for SMBus any individual SCn/SDn channel.

Depending on the application, voltage translation of the I2C bus can also be…
Part Number: PCA9546A Hello Team,
Can you share with us the thermal resistance of PCA9546ARGVR? It seems that the datasheet only contains the R θJA Junction-to-ambient thermal resistance.

Part Number: PCA9546A Hi TIer,
We are building a proto-type board for a high-volume customers, and I understand the global part shortage but is there any chance we could request for 10 samples of PCA9546A in RGV?
Thank you,
Jason
Part Number: PCA9546A Hi TIer,
I changed the schematic based on the inputs I got from the E2E and here is the schematic.
At CH0, I have four I2C MUX connected, and here is one of them.
I am using a PMBUS to run the communication. I can write to the…
