The specified values are obtained with outputs unloaded. Note c: ICC 2 and ICC 4 are the average currents required for the duration of the respective STORE cycles (tSTORE ). Note d: E ≥ V IH will not produce standby current levels until any nonvolatile cycle in progress has timed out. AC TEST CONDITIONS CAPACITANCEe (T A = 25 °C, f = 1.0MHz) Note e: These parameters are guaranteed but not tested.

This a stress rating only, and functional operation of the device at conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Figure 1: AC Output Loading AND FIXTURE SCOPE INCLUDING 5.0V Output 30pF 480 Ohms 255 Ohms |
