Notes: 1. V_CC must be applied simultaneously or before V_PP and removed simultaneously or after V_PP.
2. V_PP must not exceed 13 V including overshoot.
3. An influence may be had upon device reliability if the device is installed or removed while V_PP =
12.5 V.
4. Do not alter V_PP either V_IL to 12.5 V or 12.5 V to V_IL when CE = low.
5. V_IL min = –0.6 V for pulse width ≤ 20 ns.
6. If V_IH is over the specified maximum value, programming operation cannot be guaranteed.
