8.2.2 Detailed Design Procedure

  1. Recommended Input Conditions:
    • For rise time and fall time specification, see (Δt/ΔV) in the Recommended Operating Conditions table.
    • For specified high and low levels, see (VIH and VIL) in the Recommended Operating Conditions table.
    • Inputs are overvoltage tolerant allowing them to go as high as (VI max) in the Recommended Operating Conditions table at any valid VCC.
  2. Recommended maximum Output Conditions:
    • Load currents must not exceed (IO max) per output and must not exceed (Continuous current through VCC or GND) total current for the part. These limits are located in the Absolute Maximum Ratings table.
    • Outputs must not be pulled above VCC.
