Part Number: PCA9544A Tool/software: Hi,
I intend to use PCA9544A I2C mux in my design for an application.
I need to connect 4 slave device (2 EEPROM and 2 Temp sensor).
EEPROM has address pins so its address can be changed, while Temp sensor has a…
Part Number: PCA9544A Tool/software: Hi team,
My customer is asking about, if there's an unused I2C channel, what connection should we make for unused SCL/SDA? e.g like what reisitance value pull up to VCC? Please share some comment on this, thank you…
Part Number: PCA9544A Tool/software: Hi team,
Could you please help share what's the difference between below two parts? Looks like some packaging difference, but not sure what's main difference about the G4.
PCA9544APWR
PCA9544APWRG4
Thanks…
Part Number: PCA9544A Hello support team,
We have a requirement for PCA9544ARGYR IC footprint and dimensions details. request you to kindly share the same.
Part Number: TCA4307 Other Parts Discussed in Thread: PCA9544A , ADS1115 Dear experts,
I will connect the TCA4307 out I2C interface to the I2C of PCA9544A. The maximum low input voltage of TCA4307 is 0.4V but I can't find the low output voltage of PCA9544A…
Part Number: PCA9544A Other Parts Discussed in Thread: TCA9800 , TCA9544A , TCA9617A , TCA9617B Hi,
In the data sheet, the condition for VOL = 0.4V is IOL = 3mA, but do you have any data on the VOL characteristic value under the condition of 3mA or less…
Part Number: PCA9544A Hi Team,
I'm not able to find the package dimensions for the 20-pin RGY package on the datasheet or our other package tools on TI.com.
There was one mechanical drawing that I found, but it did not have the dimensions outlined…
Part Number: PCA9544A Hi,
There is a circuit where PCA9544ARGYR is being used and after testing with three different units in two different boards (2 units in one pcb, one unit in the second pcb) the conclusion is that somehow there is a point that is…
Part Number: PCA9544A Currently we are using the PCA9544APWR Mux for our project. There is a concern regarding the supply voltage Vcc. All the SMBus lines are pulled up to 3.3V. So can the supply voltage Vcc be 3.3V? From the graph 9.2 in the part datasheet…
Part Number: PCA9544A Hi Team,
A customer has found the CPU's I2C timing at 100kHz can only get ~4.6us for Tsts :I2C start or repeated start condition setup time, less than 4.7us min from PCA9544A spec.
However, PCA9544A also support 0.6us min for…
