1. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit conditions and are not referenced
to output voltage levels.
2. At any given temperature and voltage condition, tHZ(Max.) is less than tLZ(Min.) both for a given device and from device
to device interconnection.
3. Do not access device with cycle timing shorter than tRC(tWC) for continuous periods > 20us.
