Cautions 1. VDD should be applied before VPP, and removed after VPP.
2. VPP must not exceed +13.5 V including overshoot.
3. Reliability may be adversely affected if removal/reinsertion is performed while + 12.5 V is being
applied to VPP.

Notes 1. If you want to read within the range of tACC, make the OE input delay time from the fall of CE a maximum of tACC–
tOE.
2. tDF is the time from when either OE or CE first reaches VIH.
