Note(READ CYCLE):
1. t
CHZ
and t
OHZ
are defined as the time at which the outputs achieve the open circuit conditions and arenot
referenced to output voltage levels.
2. At any given temperature and voltage condition, t
CHZ
max. is less than t
CLZ
min. both for a given device
and from device to device.
3. /WE is high for the read cycle.
