Maximum Ratings

(Above which the useful life may be impaired.

For user guidelines, not tested.)

Voltage range applied to any output in the

Voltage range applied to any output in the

Continous Current through each VCC or GND pin ............ ±100mA

Package thermal impedance,

package V ... 94°C/W

1. Input negative-voltage and output voltage ratings may be exceeded if the

input and output clamp current ratings are observed.

2. This value is limited to 6.5V maximum.

3. The package thermal impedance is calculated in accordance with JESD

51.

Notes:

Stresses greater than those listed under MAXIMUM RATINGS may

cause permanent damage to the device. This is a stress rating only and

functional operation of the device at these or any other conditions above

those indicated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions for extended

periods may affect reliability.
