Hi all, I'm looking for a datasheet on an SFC400 ET and SFC474 ET IC. Date from around mid 70's to mid 80's?
According ecadata.de the SC474ET is a dual f/f with preset and clear, so I assume it's a 7474? And they also reckon the 400 is a quad 2 input nand, so I assume it's a 7400.
Can anyone confirm that with a datasheet?
Thanks Greg
