CAT34TS04 Digital Output Temperature Sensor with On-board SPD EEPROM Description CAT34TS04 Table 1. ABSOLUTE MAXIMUM RATINGS Parameter Rating Units Operating Temperature 45 to +130 C Storage Temperature 65 to +150 C Voltage on any pin (except A ) with respect to Ground (Note 1) 0.5 to +6.5 V 0 Voltage on pin A with respect to Ground 0.5 to +10.5 V 0 Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. The DC input voltage on any pin should not be lower than 0.5 V or higher than V + 0.5 V. The A pin can be raised to a HV level for SWP CC 0 command execution. SCL and SDA inputs can be raised to the maximum limit, irrespective of V . CC Table 2.

Power Dissipation is defined as P = (T T )/ , where T is the junction temperature and T is the ambient temperature. The thermal J J A JA J A resistance value refers to the case of a package being used on a standard 2 layer PCB. Table 4. D.C.
