Dear support team

My customer want to use SN74AHC1G86-Q1, and input transition time of signal is about 1us/V @ Vin=5V.

What kind of problem do you have when transition time is 1us/V?

(For example, Does current consumption increase?)

Hi Tomohiro san,

There could be issues from power consumption being higher , oscillations in the output during transition and false transitions maybe .

A solution to avoid this would be to use Schmitt trigger inputs which tolerate slower input transition .
