Hi all,

I'm looking for a datasheet for this IC or eventually a replacement type...

The IC is used in a temperature control circuit.

It's not a good sign when google doesn't give a single hit :cry:

SL series chips were made by Plessey (not sure about the spelling!), I seem to remember they ceased to exist some time ago.
 
Yes, it's pretty old, but very flexible circuit.I've scanned from my old book... i mean this better as nothing.
Nigel, please correct the text of blocks, i've translated from hungarian...
