Hello,
Everybody knows a 4001 is a quad NOR gate, but is there something specific about a 4001PC ?
I can't find any reference to 'PC', just lots of 'B' and 'UB'.
The chip is in the blanking circuit of a vintage miniature CRT scope.
Pins 3 and 4 are both at 0v wrt pin 7, so I think it's broken, but I don't want to remove it till I know what to put in it's place.
Cheers,
Buzby
