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…
Part Number: PCA9546A Hi team
Customer need socket that can use instead of PCA9546A and its hight is less than 1mm.
Could you tell me parts number that meet customer's demand.
Best regards,
Yajima
Part Number: PCA9546A Hi,
I would like the connect the #RESET pin on the PCA9546A to an active-high enable line which is routed to the enable pins of a number of I2C slave devices downstream of the PCA9546A.
This would mean that the #RESET pin would…
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.
Regards,
Renan
Part Number: PCA9546A A few questions about reset:
The data sheet 8.4.1 states "The /RESET input must be connected to VCC through a pull-up resistor". I have a design where the /RESET line is driven from a TTL output from an MCU. The MCU and PCA9546A…
Part Number: PCA9546A Hi,
Good Day. What signal type (SCL, SDA, SC*, SD*) for these pins? Input, Output, Input/Output? I know that these pins are Input/Output signal type but the customer confuse on page 1, 13, 21 diagram on he datasheet when the arrow…
Part Number: PCA9546A We are testing OSEPP I²C Expansion Shield, the board is powered by connect Pin3 of JP5 to 5V and pin4 of JP5 to GND. without connect to another devices, the pin15 of PCA9546 'SEN_SDA' is held low. Can you enlighten me what could…
Part Number: PCA9546A Hello,
We do not understand exactly how I2C slaves are addressed on the other side of the PCA9546A switch. We understand that you first address the control register on the I2C switch and then enable one or more slave channels.…
Part Number: PCA9546A Dear Sirs:
There is one question about I2C mux application, would like to clarify that, on our product, applied for 2 cases situation, as below show situation1 & situation2.
For situation1, discovered symptom when try enable…
Part Number: PCA9546A Other Parts Discussed in Thread: PCA9548A i would like to learn the following info from I2C communication feature:
1) what is the most frequent failure mode incurred in I2C communication ?
2) what is the stress test to access…
