48 / 66 page  µPD75P3018A 46 Data Sheet U11917EJ2V1DS DC Programming Characteristics (TA = 25 ±5°C, VDD = 6.0 ±0.25 V, VPP = 12.5 ±0.3 V, VSS = 0 V) Parameter Symbol Conditions MIN. TYP. MAX. Unit High-level input voltage VIH1 Pins other than X1, X2 0.7VDD VDD V VIH2 X1, X2 VDD – 0.5 VDD V Low-level input voltage VIL1 Pins other than X1, X2 0 0.3VDD V VIL2 X1, X2 0 0.4 V Input leakage current ILI VIN = VIL or VIH 10 µA High-level output voltage VOH IOH = –1 mA VDD – 1.0 V Low-level output voltage VOL IOL = 1.6 mA 0.4 V VDD supply current IDD 30 mA VPP supply current IPP MD0 = VIL, MD1 = VIH 30 mA Cautions 1. Ensure that VPP does not exceed +13.5 V including overshoot. 2. VDD must be applied before VPP, and cut after VPP.
