and 1.7 V
≤

DDQ
≤

,
V
DDQ
, followed by signal inputs. The power down sequence
must be the reverse. V

.
Most speed grades and configurations of this device are offered in both Commercial and Industrial Temperature ranges. The part number
of Industrial Temperature Range versions end the character “I”. Unless otherwise noted, all performance specifications quoted are evalu-
ated for worst case in the temperature range marked on the device.
