data sheet information is not sufficient for us: input-to-ouput delay : 2.4ns..8.5ns @-40°C.. 85°C
a) Can you supply any information (e.g. Jitter, Maximum Drift) about short-time (up to 10 minutes) deviation in input-to-output-delay ?
assumption: VCC and temperature are stable
b) Can you supply information about the input-to-output-delay characteristics of this device. E.g. the behavior of the deviation: Is it constant for a given individual device or does it change under certain operating conditions e.g. after power interruption and following power-up ?
