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