Notes:
1. VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP.
2. VPP may be connected directly to VCC, except during programming. The supply current would then be the sum of ICC and
IPP.

Notes:
1. Timing measurement reference level is 1.5V for -45 devices. Input AC drive levels are VIL = 0.0V and VIH = 3.0V. Timing measure-
ment reference levels for all other speed grades are VOL = 0.8V and VOH = 2.0V. Input AC drive levels are VIL = 0.45V and VIH = 2.4V.
2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE.
3. OE may be delayed up to tACC - tOE after the address is valid without impact on tACC.
4. This parameter is only sampled, and is not 100% tested.
5. Output float is defined as the point when data is no longer driven.
