An Intersil 7235 is a 4 digit vacuum fluorescent driver chip, 40 pins. Input
= mux. BCD/hex data.
A 7236 is a 4 1/2 digit counter with a vacuum fluorescent driver like the 7235.
Interesting that they have a common eval. board, my old Intersil cat. just
says an evaluation kit is available for each one (separate numbers).
