Notes
2. See the last page of this specification for Group A subgroup testing information.
3. See the “Introduction to CMOS PROMs” section of the Cypress 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.
