Table 7. Read and Standby Mode AC Characteristics
Note: 1. Test conditions assume transition timing reference level = 0.3V
CC
or 0.7V
CC
.
2. At any given temperature and voltage condition, t
GHQZ
is less than t
GLQX
and t
EHQZ
is less than t
ELQX
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.
4. Tested initially and after any design or process changes that may affect these parameters.
