5V ELECTRICAL CHARACTERISTICS
The ● denotes specifications which apply over the full operating
temperature range, otherwise specifications are at T
A
= 25°C. (Note 3)
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.
