Notes:
1.
VIL (min.) = –2.0V for pulse durations of less than 20 ns.
2.
TA is the case temperature.
3.
Not more than one output should be shorted at one time. Duration of the short circuit should not exceed 30 seconds.
4.
Tested initially and after any design or process changes that may affect these parameters.
