Part Number: TCA9548A-Q1 Other Parts Discussed in Thread: TCA9548A , Hello,
I have a few questions about TCA9548A and TCA9548A-Q1 (Automotive).
In TCA9548A datasheet (SCPS207H-revised September 2024), it is indicated :
Ta - Operating free-air…
Part Number: TCA9548A Hello
I encountered some problems when using the TCA9548A. My schematic diagram is as follows:
All pull-up resistors are 4.7K.Only channel 5 has a voltage of 1.8V.
During the debugging process, all the 3.3V channels were…
Part Number: TCA9548A
I am using eight TCA9548A multiplexers to communicate with 59 LIS3MDL sensors. Each TCA9548A has all eight downstream (low-side) I²C buses pulled up, and the upstream (high-side) bus for each multiplexer is also pulled up.
I…
Part Number: TCA9548A Tool/software: The Vol, Vih, Vil mentioned in the datasheets are for SCL and SDA lines which are the input for the ic, what is the VOL,VIH,VIL of SC0- SC7 and SD0-SD7 lines
Part Number: TCA9548A Hello everyone,
I am working on an I2C communication issue involving a PIC16LF18857 , a TCA9548A I2C multiplexer , and downstream I2C sensors (e.g. SHT4x). The hardware works correctly when driven by an ESP32 (MicroPython), but…
Part Number: TCA9548A Tool/software: Hi Teams
My application shows on the picture below.
Q1: what is VIL/VIH parameter on SDx/SCx side?
Since table 5.3 just shows the SDA/SCL(host side) sepc.
Q2: what is the VOL spec on SCx/SDx side?
Fig 5 shows…
Part Number: TCA9548A Other Parts Discussed in Thread: BQ25756 Tool/software: Issue to switch channels one by one using TCA9548A with address 0x77 connected with 4 other I2C devices (BQ25756).
1st time channel-1 selected as 0x01 data is properly write…
Part Number: TCA9548A Hi all,
In my latest production batch I received a lot of complains about having issues with the I2C bus. When debugging I noticed the TCA9548APWR switch is not responding to any commands.
Then I started noticing difference in…
Part Number: TCA9548A Hi Arya
I am just asking if I connect VCC with 3.3V then can we use Downstream ports (Slave I2C Ports) with 5V device (Pulled up with 5V) and 3.3V devices (Pulled up with 3.3V)
Upstream (Master I2C Port) port is connected…
Part Number: TCA9548A Hi
We are using part TCA9548ARGER in our new design. VCC is connected with 3.3V and Main communication lines are also at 3.3V level and pulled up with 3.3V supply. We need different Pull up supply (5V and 3.3V) at Downstream ports…
