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.
For devices using the synchronous enable, the device must be clocked after applying these voltages to perform this measurement.
5.
See Introduction to CMOS PROMs in this Data Book for general information on testing.
6.
For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
