NOTES
(READ CYCLE)
1.
t
HZ
and
t
OHZ
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,
t
HZ
(Max.) is less than
t
LZ
(Min.) both for a given device and from device to device
interconnection.
