NOTE:
1. See Figure 9, āAC Waveform: SRAM Read Operationsā on page 36.
2. At any given temperature and voltage condition, tHZ (Max) is less than and tLZ (Max) both for a given
device and from device to device interconnection.
3. Sampled, but not 100% tested.
4. Timings of 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.
