I/O Combinatorial Logic

• OAND2

  • Can be used as a generic two-input function generator or MUX
  • One input can be driven by IOB output clock signal
  • Requires library components beginning with “O”
  • F input pin is faster than IO pin

• OMUX2

  • Fast output signal (from output clock pin) MUXes IOB output or clock enable pins to pad
  • Effectively doubles the number of device outputs without requiring a larger, more expensive package
  • Pin-to-pin delay is less than 6 ns
