Must tri-state outputs and use an external resistor to pull up to 5V To drive 5V CMOS-level inputs, a pull-up resistor must be applied to the 5V Virtex output. Priorto driving a logic 1 data signal, the Virtex output must be tri-stated. This ensures…
http://www.altera.com/literature/hb/max2/max2_mii51009.pdf The open-drain pin never drives high, only low or tri-state. When the open-drain pin is active, it drives low. When the open-drain pin is inactive, the pin is tri-stated and the trace pulls u…
