Signetics was acquired in 1975 by Philips. The current Signetics is a
Korean assembly and test company which traces its lineage from the
original Signetics. If there is actually a Signetics logo on the chip
and the date code is from the late '90s, the number is probably a
"house" number...
You might look at <

chip. There are a number of "S"s that are similar to the original
Signetics log.
