#132783 - not an Atmel issue Responding to: ???'s previous message |
every chip has a Vil min and a Vil max plus a Vih min and a Vih max and that is your "noise window" If you compare datasheets you will see that these values are pretty mich the same for all derivatives (at the same Vcc).
what you need to do is described in this FAQ http://www.8052.com/faqs.phtml?FAQ=119926 and when a contactor handles line current of 30amps per phase and the controller circuit is quite near to it. you can not skimp an any of it. Erik |
