Notes:
2. V
IL
(min.) = –3.0V for pulse durations less than 30 ns.
3. Not more than 1 output should be shorted at one time. Duration of the short circuit should not exceed 30 seconds.
4. A pull-up resistor to V
CC
on the CE input is required to keep the device deselected during V
CC
power-up, otherwise I
SB
will exceed values given.
5. Tested initially and after any design or process changes that may affect these parameters.
