Notes:
2.
Contact a Cypress representative for information on industrial temperature range specifications.
3.
TA is the “instant on” case temperature.
4.
See the last page of this specification for Group A subgroup testing information.
5.
IOL=12.0 mA for military devices.
6.
For test purposes, not more than one output at a time should be shorted. Short circuit test duration should not exceed 30 seconds.
7.
See Introduction to CMOS PROMs in this Data Book for general information on testing.
