Part Number: PCA9517 Other Parts Discussed in Thread: TCA9517 , TCA9803 Q1: Can VCCA and VCCB are working at same voltage level? for example both sides are 3.3V
Q2. I have capactured CLK / DATA waveforms, it seems low level can not reach as low as 0V in…
Part Number: PCA9517 I have two questions about the PCA9517. (1) Do you have any requirements regarding "the power off sequence"? (2) Do you have any requirements regarding "the timing of power and EN"?
Part Number: PCA9517 Hi
According to the datasheet, B side has offset of VOL about 0.51V and A side VOL is about 0.1V.
As you see waveforms below, B side SDA keeps low (0.51V) but A side did not drop to VOL occasionally. Why?
CH1 A side SDA
CH2 B side…
Part Number: PCA9517 Hi,
I have used the TCA9517DGKR part in one of our products which is been supported by us for the last 4 years, now may due to the covid situation we are unable to source this part.
So I am thinking to use PCA9517DGKR in place of…
Hello,
Sorry I didn't see your message until now.
Is this the A side of B side of the device? If A side, then what is the pull up resistor value you are using?
