Hi Lisa,
The SCx and SDx pins of the PCA9548A should be pulled up even when not in use due to the nature of the I2C protocol and the design of the PCA9548A itself.
It's recommended to use pull-up resistors even when not in use to ensure that the I2C bus…
Part Number: PCA9548A I want to check if I can put a device with the same address on the master bus as on one or more slave buses. My concern is - it may create a conflict. Am I correct?
Part Number: PCA9548A Other Parts Discussed in Thread: TCA9803 Team,
I want to check with you if PCA9548 has driving ability, or only a MUX function when connected to master.
Background is, my customer is using PCA9548 as I2C salve together with other…
Part Number: PCA9548A Other Parts Discussed in Thread: TCA9548A Dear TI Team:
Checked from PCA9548A datasheet, It shows it also supports voltage Translator function.
There are some items need your help.Thanks!
Pls check the picture as below, The PCA9548A…
Hello Max,
Hmm, I was wondering how do we know that the PCA9548A holding the SDA bus low and not some other device downstream on the i2c bus?
The key here is to figure out which device on the i2c bus is pulling the bus to a stuck low condition. It could…
Part Number: PCA9548A For an application where one master access 8 slaves/sensors, I have designed in the PCA9548APW I2C switch.
Our master will use 3.0V or 3.3V, but the slaves will have 2.5V supply.
When reading the datasheet, I got a little confused…
Part Number: PCA9548A Hi,
I’m having some difficulty identifying some Mil Spec. components for some IC’s !
I noticed that there are what is called Storage Temperature for some of these parts. So the question I have:
what will happen if the…

1. When we frequently access the two channels of PCA9548APWR through I2C, when accessing the two channels, the three channels will be opened with probability, and the waveform is shown in the following…
Part Number: PCA9548A Other Parts Discussed in Thread: MSP-EXP430G2ET Hi Sirs
With PCA9548A, MCU would like to control 4 sensors with same I2C ID.
=> How to evaluate the I2C time tolerance are enough?
PS. Attached are the MCU, Sensors time index. …
