Shaded area contains preliminary information.
Notes:
1. V(min.) = −2.0V for pulse durations of less than 20 ns.
2. TA is the “instant on” case temperature.
3. See the last page of this specification for Group A subgroup testing information.
4. Not more than one output should be shorted at one time. Duration of the short circuit should not exceed 30 seconds.
5. 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.
