ESD CAUTION

1 Input pins have clamp diodes to the supply pins. Input current should be

limited to 10 mA or less whenever input signals exceed either power supply

rail by 0.3 V.

2 Inputs are protected against high differential voltages by internal 1 kΩ series

resistors and back-to-back diode-connected N-MOSFETs (with a typical VT of

1.25 V for VCM of 0 V).

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
