NOTES:
CE » and OE » are switched low after Power-Up.
1. The power supply may start to switch concurrently with RP » going Low. RP » is required to stay low, until V_CC stays at
recommended operating voltage.
2. The address access time and RP » high to data valid time are shown for 3.3 V V_CC operation. Refer to the
AC Characteristics Read Only Operations also.
