Hello,

Cant figure out what your name is - Nattapon or Ake ?

Anyway did you read the two replies to your earlier post ? and in the second post this was the reply :

Why are you using it? The Phillips 8xc552/554 has a similar (though not identical) timer 2 and is pretty much the same chip otherwise. They are available in small quantities from Arrow Electronics here in the USA.


So, you have been warned that it is obsolete and also have been given an alternative. And you go and post another demand in a dead thread.
