DC Characteristics (VCC = 6.25 V ± 0.25 V, VPP =12.5 V ± 0.3 V, Ta=25°C ± 5°C)
Parameter Symbol Min Typ Max Unit Test conditions
———————————————————————————————————————————
Input leakage current ILI — — 2 µA Vin = 6.5 V/0.45 V
———————————————————————————————————————————
VPP supply current IPP — — 40 mA CE = VIL
———————————————————————————————————————————
Operating VCC current ICC — — 50 mA
———————————————————————————————————————————
Input voltage VIL –0.1*5— 0.8 V

VIH 2.2 — VCC +0.5*6V
———————————————————————————————————————————
Output voltage VOL — — 0.45 V IOL = 2.1 mA

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