Notes:
1. The voltage on any input or I/O pin cannot exceed the power pin during power-up.
2. See the last page of this specification for Group A subgroup testing information.
3. See Introduction to CMOS PROMs in this Data Book for general information on testing.
4. For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
