   RCA made transistor arrays in DIP packages; the white ceramic dates it   
   from the early days, but plastic DIPs might still be in production.

   the schematic section (pin numbers) is consistent with CA3046 and CA3045.   
   The CA3045 was the ceramic-package variant, but specifications are very similar   
   (CA3045F was the brown-ceramic frit seal package, you've got the CA3045 with   
   white ceramic).   
   The IC has five, not just four, transistors.
