Part Number: TCA6408A-Q1
Hi Team,
I am using TCA6408A-Q1 part only for HIGH and LOW detection by using a ON-OFF Switch at P0 and P1 Pin. I have pulled it up with 3.3V and added on-off switch with it for sensing High and Low (for more clarification i have…
Part Number: TCA6408A Hi all!
I was using the tca6408A UQFN package in my design.
As it stands, there are no TCA6408A available in any package...
I noticed the tca6408A-Q1 (TSSOP package) - Can anyone tell me if it is a direct alternative? if not, are…

Part Number: TCA6408A-Q1 Hello,
I want to ask what the power consumption of TCA6408A-Q1 is when it's configured as output?
When it's input, the power consumption is low, customer want to keep input & output function normal when SOC powered off, so…
Part Number: TCA6408A Hello,
Our customer has a question about I2C signal line condition in TCA6408A RESET initialization process. Could you let us know whether you experienced pulling I2C line low during RESET initialization process.
Best regards,
Part Number: TCA6408A-Q1 Hi Expert,
Our customer need I2C I/O expander in camera module. They have very limit space. Do you have smaller device supporting 2CH or 4CH? Automotive chip is needed. Thanks.

Part Number: TCA6408A Hello,
I have question about the TCA6408A.
I am currently using it with the following setup : Vccp = Vcci = 1.8V.
On the datasheet Section 6.5, the VOH of the P-port is mentioned and for Vccp = 1.65V, the min VOH is 1.2V for IOH…
Part Number: TCA6408A Hi.
I have a question.
If I2C tVD_DAT is not followed, what happens?
I think tSU_DAT and tHD_DAT is followed, there is no problem of data error.
Or could there be any problems?
I look forward to hearing from you soon.Thank you. …
Part Number: TCA6408A Hi. I have a related question.
While the main control computer, and its I2C bus and accompanying power supply for the VCCI pin is powered down, the TCA6408A output port needs to remain high.
If \RESET pin is pull to VCCP (not pull…

Hi,
I have a question.
If the IO ports are unused, I should set them Output (and open), or set them Input with pull up resister, right?
(I think it is necessary not to float to avoid through current.)
If possible, I just want to…
