0 400 Unit V mW Tstg * Storage Temperature -65 to +150 °C Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the Recommended Operating Conditions.
RECOMMENDED OPERATING CONDITIONS Symbol VCC TA Parameter DC Supply Voltage (Referenced to GND) Operating Temperature Min 13.
0 -45 Max 29.
0 +65 Unit V °C This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit.
For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC.
