3 / 7 page ![]() 3 HV57708 DC Electrical Characteristics (Over operating supply voltages and temperature, unless otherwise noted) Symbol Parameter Min Max Units Conditions I DD V DD supply current - 15 mA V DD = VDD max, fCLK = 8MHz I PP High voltage supply current - 100 µA Outputs high - 100 µA Outputs low I DDQ Quiescent V DD supply current - 100 µA All V IN = VDD V OH High level output HV OUT 65 - V I O = -15mA, VPP = +80V D OUT V DD - 0.5V - V I O = -100µA V OL Low level output HV OUT - 7.0 V I O = 12mA, VPP = +80V D OUT - 0.5 V I O = 100µA I IH High-level logic input current - 1.0 µA V IH = VDD I IL Low-level logic input current - -1.0 µA V IL = 0V V OC High voltage clamp diode - 1.0 V I OC = 1.0mA AC Electrical Characteristics (T A = 85°C max. Logic signal inputs and Data inputs have t r, tf ≤ 5ns [10% and 90% points]) Symbol Parameter Min Max Units Conditions f CLK Clock frequency - 8 MHz Per register t WL, tWH Clock width high or low 62 - ns --- t SU Data set-up time before clock rises 10 - ns --- t H Data hold time after clock rises 15 - ns --- t ON, tOFF Time from latch enable to HV OUT - 500 ns C L = 15pF t DHL Delay time clock to data high to low - 70 ns C L = 15pF t DLH Delay time clock to data low to high - 70 ns C L = 15pF t DLE* Delay time clock to LE low to high 25 - ns --- t WLE LE pulse width 25 - ns --- t SLE LE set-up time before clock rises 0 - ns --- * t DLE is not required but is recommended to produce stable HV outputs and thus minimize power dissipation and current spikes (allows internal SR output to stabilize). |
