Datasheet SLC5554E Timer

[carloslouis]

Hi,
I' m looking for the datasheet of an old timer/clock IC type SLC5554 E...
Would help me a lot if someone could give me some information of these IC!

Thanks a lot in advance
Louis

This is most likely a variant of the ubiquitous 555 timer IC. A dedicated datasheet for the SLC555 can be found here.
Any other 555 datasheet will probably do. Note that there are basically two different variants: The older bipolar 555 and the newer CMOS 555 with different properties. Teh SLC555 seems to be of the bipolar type.

Hi, thanks a lot for the information! Unfortunately I made a mistake on the description....It is in reality a t SLC 5455 E !
It is a 40 pins IC, used normaly in the automotive section. Thanks in advance
