Re: Source for Sony SBX1602A Serial to Parallel chip??



A few more notes:

1. The SONY (and THOMPSON) 1602A "chip" is actually a hybrid, i.e. there
   is a small substrate inside with a number of components mounted to it.
   Hybrids are generally less reliable than a monolithic chip due to the 
   increased complexity.
2. The internal contamination failure mode that Bill Hogan mentioned is 
   well known around here - it even has a name: the "Purple Plague". 
   This problem seems to be exacerbated by heat.
3. Apparently SONY has discontinued the part (yikes), but THOMPSON still
   makes it. The THOMPSON pn is STV1602A, I believe the contact is
   THOMPSON BROADCAST.
