Part Number: TCA9535 Hi there
We just want to detect TI TCA9535RGER. However I2Cdetect -y -r found no such device
Please check if the following is correct or not.
PS. SCL, SDA, and INT# have pull up resistors on the other page.
Part Number: TCA9535 Tool/software: In the TCA9535, do the SCL and SDA pins have a high-side clamp diode protection? "SCL → Diode → VCC"
Also, please tell me the absolute maximum rated voltage of the SCL and SDA pins.
I was curious because…
Part Number: TCA9535 Dear Specialists,
My cusomer is considering TCA9535 and has a question.
I would be grateful if you could advise.

could u kindly help to review the schematic? thanks!
Part Number: TCA9535 Tool/software: Hi Team,
The datasheet requires ticf & tocf as below. based on VCC = 3.3V, the min ticf and tocf is ~12ns.
While the real test in my customer board is 3ns. is there any risk? if yes, how to remove this risk? …

Question from Nvidia, TCA9555 is pulled up by internal resistor during POR. Can you confirm the internal pull up resistor during POR (inside IC)? Thanks!
Part Number: TCA9535 Other Parts Discussed in Thread: TCA9539-Q1 Tool/software: Hi Team
I'm pretty sure the answer is yes but was hoping to get confirmation. Can I pull-up the INT output to +3V3 while the remainder of the IC operates from +5V?
Also…
