Notes:
1.
Contact a Cypress representative for industrial temperature range specifications.
2.
TA is the “instant on” case temperature
3.
See Introduction to CMOS PROMs in this Data Book for general information on testing.
4.
See the last page of this specification for Group A subgroup testing information.
5.
For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
