In the thread 'Surf Pi Pro', au1 shared their experience with the LM358N and LM358P chips:
I have ordered both TLC555 and LM358N to replace the NE555 and LM358P on my 1.2 longboard as a test. However, the IC seller has sent the same LM358P I was already using and is adamant they're 100% the same operationally.
Can anyone confirm any difference in these ICs beyond who manufactured the chip?
Many thanks.

I hate to be the bearer of bad news, but thats your problem. You need a TLC555 instead of NE555. If you look at the data-sheet there is a big difference. If I recall correctly the TLC555 runs at 2.1 MHZ.
And the LM358P only has about half the gain as the LM358N. I have 50 LM358P here and trust me, they won't work. It took me about a week to figure this out.
