I have an old design that I must convert, and it has some old Teledyne parts on it. The 333AL/CL is an old hex inverter. I need to know what the parameters of this part are.. Open collector or totem pole? Max current on output? Max V on VCC? Thresholds on inputs? Pullup in input? If someone has an old databook from Teledyne, I will buy or trade for it.. I will even pickup shipping. Chris~ -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
