Notes:
1.
Contact a Cypress representative for industrial temperature range specifications.
2.
TA is the “instant on” case temperature.
3.
See the last page of this specification for Group A subgroup testing information.
4.
See Introduction to CMOS PROMs for general information on testing.
5.
Short circuit test should not exceed 30 seconds.
