Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 Hi team, Good day.
What is the I2C rise and fall time of CLOCK and DATA signals for TCA9517-Q1?
Regards, Carlo
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 Dear Team
My customer consider to use Level-Shifting I2C Bus Repeater,
Because the cable length will more than 1M, would you please help to check if we use this parts can support how long…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 Dear all,
i'm designing the bus for an I2C multi-master protocol.
I read on the datasheet that TCA9517-Q1 accomodates the I2C multi-master protocol.
Is it confirmed? if yes, are there…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 Hello Team,
In my design VCCA will be power off faster than VCCB, and as per datasheet during power off stage all pins goes into high impedance state.
So is there any effect of this VCCA…
Thanks again
1) The reason I used TCA980x on first diagram is to have all desired voltages(1.65V/1.8V/2.5V/3.3V) available both Board1 and Board2 since the single use of TCA9517 on both sides does not provide 1.65V and 1.8V as an output on B side. This can…
Thank you for the reply.
I confirmed that there are no problems with 400kHz.
Please let me ask some additional question.
about connection I2C buffer
Q1. Is this possible? Connect with SDAB-SDAB(SCLB-SCLB), SDAA-SDAA (SCLA-SCLA).
*reason : more better…
Hello,
we are using side A VCCA (Input) for 3.3v Master Controller and Side B VCCB (Output) for Slave RTC but when we are not communicating or Controller shutdown (3.3V Off ) at that time leakage current through the VCCB is approximately 1.6mA which is…
Part Number: TCA9517-Q1 Other Parts Discussed in Thread: TCA9517 Hello,
If i plan to use the TCA9517 in series, to connect an I2C bus on multiple boards, is the design intent shown in figure 9 in the datasheet to use the same power source for VCCA and…
Part Number: TCA9517-Q1 Hi,
We have a 3.3V and 1.8V I2C Level shift design in our project, 3.3V is master at the B-side, 1.8V is slave at the A-side.
I saw the non monotonic waveform at the B-side input measurement. (please refer below)
Why does the…
