Part Number: TCA8418
Hi, I am designed a custom PCB and I am facing a very small issue related to program if someone can help me with it. It is Arduino Code. I know it is out of your jurisdiction but I think someone can help me with it because I also…
Part Number: TCA8418 I have a design that uses the TCA8418 to drive a 7x10 keyboard matrix. Whenever the key in ROW1 COL9 is pressed I get two key events: 20 and 98. I have confirmed these both result in a K_INT flag being set, it is not a GPI_INT flag…
Hi, Yes, I know how to use the I2C library. I am finalizing a PCB and soon, it will be done then I will focus on playing with the programming part. I hope it will not a hectic work to interface this IC with Arduino.
Part Number: TCA8418 hi TI
Unable to read the key interrupt, INT pin (input, PULLUP) has not changed, RST (output, high level), please check the schematic diagram and program for any problems,
Thank you。

Part Number: TCA8418E We need the key scanning frequency of around 6-10ms, But We are not able to find the register in the datasheet to change the key scan timing.
Is it possible to change the key scanning frequency if the TCA8418E ?
Part Number: TCA8418 Hello team,
Now we switch the TCA8418E to TCA8418, but from 8418E we see the 15kV EDS spcific in datasheet, and no clarify in 8418.
So, could we can use 8418E?
Thanks!
Part Number: TCA8418 Hello:
My customer uses TCA8418RTWR.Sometimes it is found that the key fails, and the measurement result is K_ Int is always low,What's the problem? Thanks.
Part Number: TCA8418E Other Parts Discussed in Thread: TCA8418 , LM8330 Hello
TCA8418E and TCA8418 are out of stock,Would you please recommand other TI chip to replace them,Thanks
