wtd: datasheet for sfc400 and sfc474

Jun 27, 2009 3 Replies

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

Is there a manufacturer logo on the devices?

If so, have a look to see if it matches any here
