[Test-Equipment] Help Finding Chip

Wed, 9 Apr 2003 12:43:23 -0600

Dave:

In a "replacement part cross reference" that was provided 
to me some time ago by Mark Pilant N1VQW, the HP part 
number 1820-1188 crosses to a CD4046AF.  

Could you check the part number again, and let me know so
that I can recheck this cross reference for you?

Thanks de John
