Notes:
1. Minimum voltage is equal to –3.0V for pulse durations less than 30 ns.
2. 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.
3. Tested initially and after any design or process changes that may affect these parameters.
