7.2.1 Design Requirements

  1. Recommended Input Conditions:
    • For specified high and low levels, see VIH and VIL in Section 5.3.
    • Inputs and outputs are overvoltage tolerant slowing them to go as high as 4.6V at any valid VCC.
  2. Recommended Output Conditions:
    • Load currents should not exceed ±128mA per channel.
  3. Frequency Selection Criterion:
    • Maximum frequency tested is 500MHz.
    • Added trace resistance/capacitance can reduce maximum frequency capability; use layout practices as directed in Section 7.3.
