Note: 1. Test conditions assume transition timing reference level = 0.3VCC or 0.7VCC.
2. At any given temperature and voltage condition, tEHQZ is less than tELQX and tGHQZ is less than tGLQX for any given device.
3. These parameters are defined as the time at which the outputs achieve the open circuit conditions and are not referenced to output
voltage levels.
