TLC555-Q1: The noise immunity of trigger input

Part Number: TLC555-Q1
Other Parts Discussed in Thread: TLC555

Hi team,

Could you tell me how much minimum time of "TRIG H" makes "OUT H"?

We are concern about the noise immunity of "TRIG" input. Is it deglitch filter on "TRIG" pin and how much is the filter time?

Regards,
Ochi

Hi team,

Sorry for typo.

Could you tell me how much minimum time of "TRIG L" makes "OUT H"?

Hello,

There are recommended values for the TRIG L time in this FAQ. The TLC555-Q1 would be the same as the TLC555.

I am not aware of any filter on the inputs.
