Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: If the part is stored outside of the specific operating temperature

range, the output may shift due to hysteresis.

Note 3: ESD (Electrostatic Discharge) sensitive device. Use proper ESD

handling precautions.

Note 4: Output requires 0.1µF for operating current greater than 1mA.

Note 5: This parameter is guaranteed by “reverse breakdown change with

current” test.

Note 6: Peak-to-peak noise is measured with a single highpass filter at

0.1Hz and 2-pole lowpass filter at 10Hz.
