HY6264A Series
Note(READ CYCLE):
1.tCHZ 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, tCHZ max. is less than tCLZ min. both for a given
device and from device to device.
3./WE is high for the read cycle.
