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