Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: For the metal can package, derate at 6.8mW/°C for operation at
ambient temperatures above 100°C; for the hermetic dual-in-line package,
derate at 9mW/°C for operation at ambient temperatures above 105°C.
Note 3: Guaranteed by design, but not tested.
Note 4: Sample tested at 25°C only.
Definitions:
tPD: The propagation delay measured from the time the input signal
crosses the input offset voltage to the 50% point of the output transition.
tPD(E): The propagation delay measured from the 50% point of the latch
enable signal positive transition to the 50% point of the output transition.
tS: The minimum time before the negative transition of the latch enable
signal that an input signal change must be present in order to be acquired
and held at the outputs.
tH: The minimum time after the negative transition of the latch enable
signal that the input signal must remain unchanged in order to be acquired
and held at the outputs.
tPW (E): The minimum time that the latch enable signal must be HIGH in
order to acquire and hold an input signal change.
