TCA9555: Debouncing

Tyrique Townsend

Part Number: TCA9555
Other Parts Discussed in Thread: TCA8418E

Tool/software:

I was notified by TI support that "TCA9555 does not have automatic debouncing built in. If debounce is needed, an external cap would be needed."

- Is there a drop-in replacement available that includes the debouncing?

- Do you have a reference schematic or part of the data sheet that could be referenced for the capacitor design?

1. There is no P2P device with debouncing.

Hi Tyrique,

Like Clemens suggested no p2p device with debouncing built in.

In our other thread, TCA8418E has debounce circuitry through register setting.

See Clemens reference to the application note.
