Part Number: TCA9545A Other Parts Discussed in Thread: PCA9545A Hi Team,
My cusomter face a problem that SC3/SD3 have no output. Actually, our part TCA9545APWR is P2P to another part PCA9545A(NXP). They will not face this probelm when using PCA9545A. Do you…
Part Number: TCA9545A Hi, Team
Our customer use TCA9545A and have a i2c timing issue and needs TI to clarify:
From the official i2c spec page 44( https://www.nxp.com/docs/en/user-guide/UM10204.pdf ), the tVD;DAT is 3.45uS for Standard mode, and 0.9uS for…
Part Number: TCA9545A Other Parts Discussed in Thread: PCA9306 Hi team,
Pls help on the question from my customer,
I download IBIS model of TCA9545A from TI website, and I’m a little confused about it. In datasheet, there is switch on-state resistance…
Part Number: TCA9545A Other Parts Discussed in Thread: TCA9546A , , SN74LV4052A Hi Dear,
We have an audio customer who wants to find an I2C interface solution. The specific requirement is that there are multiple chips with the same I2C address on a board…
Part Number: TCA9545A Dear Team,
When using the TCA9545A as a level shifter at the same time, if the signal input criterion conflicts with 0.7VCC, how to understand the relationship between Vdpum and Vdpux? Can the former be smaller than the latter? Thanks…
Part Number: TCA9545A Other Parts Discussed in Thread: TCA4311A Hi
We are using the TCA9545A in the following configuration (see image below), with the TCA9545A and master I2C controller powered from VCC_1, and a device on an output port powered from…
Part Number: TCA9545A Now we are debugging TCA9545A based on RK3399. At present, we only know how to open the access I2C, but we do not know how to work and whether a driver is needed. If necessary, could you help to provide Linux driver and configuration…
Part Number: TCA9545A Hi there
I have some questions about TCA9545A
1.May I ask how to measure the RON,follow is the answer on your E2E forum，Is it like this？can you show me a diagram？
[Bobby] I imagine you may need to place a small resistor before…
Part Number: TCA9545A Hi Sir:
I am very confuse about Vih max in datasheet 6.3 Recommended Operating Conditions describe.
according to table 6.3 appear that Vih is 0.7Vcc~ Vcc+0.5.
Now my question is that my circuitry is connect VCC of TCA9545A Vcc to power…
Part Number: TCA9545A Other Parts Discussed in Thread: PCA9545A Hi Team,
I have two questions about the TCA9545A.
1. Am I right in saying that the VIH/VIL specs only apply to the Master SDA/SCL lines and do not apply to the slave SDx/SCx lines?
2. …
