Part Number: TCA9517 In the TCA 9517.png there is our schematic implementation.
MCU is able to reach successfully the AT24C256 EEprom, during the acces the TCA9517 is disabled
to avoid contention .
We can see on SCL_RIM and SDA_RIM a "flat" on relative…
Part Number: TCA9517 Hi, Team
In the TCA9517 datasheet Figure 9, it shows that TCA9517 can support a " Series configuration". My customer has the following questions about this:
In Figure 9, only VCCB supply is shown, but VCCA supply is not visible…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 Hello
When i tie the EN pin to Ground, the current drain from VCCA and VCCB pins do not seem to go down by 1.5mA as stated in the datasheet.
But if i remove the TCA9517 from my pcb,…
Hi Mesut,
You're seeing two related symptoms with the TCA9517-Q1 buffer at 400 kHz:
Rise time degrades when the buffer is inserted (230 ns → 280 ns with 1.5 kΩ pull-up; improves to ~240 ns with 1.2 kΩ)
Root Cause #1: Rise Time Degradation

Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TAS5411-Q1 Hello TI fellow,
For TCA9517-Q1, why B side Vol will be raised to about 0.6V? is there any risk for 3.3V I2C interface?
Actually in our application, B side I2C is connected to TI…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 , TCA9511A , TCA9803 Hello,
We have a backfeeding issue on the I²C lines in our design. Would it be possible to use the device so that both VCCA and VCCB are powered from the B board supply…
Part Number: TCA9517-Q1 Hi Team,
We want to use TCA9517-Q1 as I2C buffer, and here are a few questions for this TCA9517-Q1 IC: (1) If the master I2C device is an I2C analog with GPIO, is this still applicable? (2) How many (3~4) device addresses are…
Part Number: TCA9517 Dear TI Engineers,
I hope you are doing well! I have an issue regarding the TCA9157 module.
Setup
I want to connect two ESP32-C3 to a single MCP23008 via I2C. There will be always only one ESP32-C3 module powered at the same…
