Notes on Pin Description:
1. All TUDX inputs and bidirectionals present minimum capacitive loading and
operate at TTL logic levels.
2. All TUDX digital outputs and bidirectionals have 2 mA drive capability, except
the INTB, SOUTT[8:0], SOUTB[8:0] outputs and D[7:0] bidirectionals, which
have 4 mA drive capability, and the DOUTL[8:0], DOUTR[8:0], AOUTL[8:0]
and AOUTR[8:0] outputs, which have 8 mA drive capability.
3. The VSSO and VSSI ground pins are not internally connected together.
Failure to connect these pins externally may cause malfunction or damage
the TUDX.
