49 / 64 page  µPD75P0076 47 Data Sheet U10232EJ1V1DS DC PROGRAMMING CHARACTERISTICS (TA = 25 ± 5˚C, VDD = 6.0 ± 0.25 V, VPP = 12.5 ± 0.3 V, VSS = 0 V) Parameter Symbol Test conditions MIN. TYP. MAX. Unit Input voltage high VIH1 Except X1, X2 0.7VDD VDD V VIH2 X1, X2 VDD–0.5 VDD V Input voltage low VIL1 Except X1, X2 0 0.3VDD V VIL2 X1, X2 0 0.4 V Input leakage current ILI VIN = VIL or VIH 10 µA Output voltage high VOH IOH = –1 mA VDD–1.0 V Output voltage low VOL IOL = 1.6 mA 0.4 V\ VDD power supply current IDD 30 mA VPP power supply current IPP MD0 = VIL, MD1 = VIH 30 mA Cautions 1. Avoid exceeding +13.5 V for VPP including the overshoot. 2. VDD must be applied before VPP, and cut after VPP. AC PROGRAMMING CHARACTERISTICS (TA = 25 ± 5˚C, VDD = 6.0 ± 0.25 V, VPP = 12.5 ± 0.3 V, VSS = 0 V) Parameter Symbol Note 1 Test conditions MIN. TYP. MAX.
