ELECTRICAL CHARACTERISTCS

Unless otherwise specified the below listed parameters' values are referred to the following conditions:

VBAT = –115V, VCC = 5V, Rlim = 53.6 kW, CODCn RC series = 100nF ±10% and 510Ω ±1%, normal temperature

range [0°C to 70°C]. The presence of an asterisk mark (*) indicates that the marked parameter must remain

within the specified tolerance in the extended temperature range [-40°C to 85°C].
