Notes
1. The voltage on any input or I/O pin cannot exceed the power pin during power-up.
2. See the “Introduction to CMOS PROMs” section of the Cypress Data Book for general information on testing.
3. For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
