Hi, everyone,
I have been having problems with the original 555 timer (version NE555). On the Internet, I found out that this is a common problem: when the power supply's voltage suddenly changes, a false triggering occurs. Also, I read about the CMOS versions of 555 and their "immunity" to this problem. I want to use a CMOS 555 timer, but in my city I can only find the LA7555 CI. Google tells me much about some versions as ICM7555, LMC555 or TLC555, but little about LA7555. Even by the datasheet I couldn't have many conclusions. Do you guys know something about the LA timer? Is it as good as the other ones seem to be? Is it worth buying?
