... 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. ...

... SCOPE (b) High -ZLoad 2.0V System timing is simplified in that the on-chip edge-triggered register allows the PROM clock to be derived directly from the system clock without introducing race conditions. The on-chip register timing requirements are similar to those of discrete registers available in the market. The CY7C235A has an asynchronous initialize input (INIT). ...
