108 / 145 page  ST7263BDx ST7263BHx ST7263BKx ST7263BE 108/145 14 Electrical characteristics 14.1 Parameter conditions Unless otherwise specified, all voltages are re- ferred to VSS. 14.1.1 Minimum and maximum values Unless otherwise specified the minimum and max- imum values are guaranteed in the worst condi- tions of ambient temperature, supply voltage and frequencies by tests in production on 100% of the devices with an ambient temperature at TA=25°C and TA=TAmax (given by the selected temperature range). Data based on characterization results, design simulation and/or technology characteristics are indicated in the table footnotes and are not tested in production. Based on characterization, the min- imum and maximum values refer to sample tests and represent the mean value plus or minus three times the standard deviation (mean±3 Σ). 14.1.2 Typical values Unless otherwise specified, typical data are based on TA=25°C, VDD=5V. They are given only as de- sign guidelines and are not tested. 14.1.3 Typical curves Unless otherwise specified, all typical curves are given only as design guidelines and are not tested. 14.1.4 Loading capacitor The loading conditions used for pin parameter measurement are shown in Figure 49. Figure 49. Pin loading conditions 14.1.5 Pin input voltage The input voltage measurement on a pin of the de- vice is described in Figure 50. Figure 50. Pin input voltage CL ST7 PIN VIN ST7 PIN |
