Part Number: PCA9306-Q1 Hi Team,
My customer is using PCA9306-Q1 as an I2C switch while VREF1=VREF2=1.8V. I have a question about the voltage selection of EN pin. Why we can't choose high logic to exceed Vref2+Vth? My understanding is that this will help…
Part Number: PCA9306-Q1 Hi Team,
This devices datasheet recommends a weak 200kΩ pull-up for the EN signal. Is there any reason why this pull-up needs to be so weak? Could we instead use a stronger pull-up, and if so, is there a minimum allowable…
Part Number: PCA9306-Q1 Hello,
The PCA9306-Q1 is used in our application as a I2C switch. Both sides of the PCA9306-Q1 are supplied with 3.3V (from the same supply) and we don't need the voltage translation functionality. The EN pin is controlled by a…
Part Number: PCA9306-Q1 Hi team,
As explained in related thread, the difference between T and I versions is the temp randge.
But the datasheet specifies -40 +105 temp range for both vestions.
Are the versions are really equal?
Part Number: PCA9306-Q1 Hi,
I am using the PCA9306-Q1 as an I2C switch using the switch enable control diagram found in the datasheet.
I wanted to know will there be any issues if I were to set both Vref1 and Vref2 to 3.3V. See the diagram below for…
Part Number: PCA9306-Q1 Hi Team,
Could you please share the following for PCA9306TDCURQ1:
Junction to Board thermal resistance / Theta jB
Junction to Case thermal resistance / Theta jC
Thanks,
Dan
Part Number: PCA9306-Q1 Hello TI experts,
My customer drew their first schematic with PCA9306-Q1. Could you review the schematic?
and here are some question.
1. they wanted to separate EN and VREF2. is it possible?
they want that VREF1 and VREF2 is already…

Part Number: PCA9306-Q1 Other Parts Discussed in Thread: PCA9306 , , TCA9800 Hello,
in my design I need to communicate with a sensor powered at 1V8, while the main I2C bus is powered at 3V3. However, the main I2C bus is not directly connected to a CPU master…
Part Number: PCA9306-Q1 Other Parts Discussed in Thread: TCA9517-Q1 Hello Team,
Q. Can PCA9306-Q1 support clock stretch in I2C communication?
In the TCA9517-Q1 datasheet, I found the device support clock stretch. However I can't find such information…
