(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of

device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or

other conditions beyond those indicated in the Operating Ratings is not implied. The recommended Operating Ratings indicate

conditions at which the device is functional and the device should not be operated beyond such conditions.

(2)

The human body model is a 100 pF capacitor discharged through a 1.5-k

Ω resistor into each pin.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur, including inoperability and degradation of

device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or

other conditions beyond those indicated in the Operating Ratings is not implied. The recommended Operating Ratings indicate

conditions at which the device is functional and the device should not be operated beyond such conditions.

(2)

The LM3406HV-Q1 can operate at an ambient temperature of up to +125°C as long as the junction temperature maximum of +150°C is

not exceeded.
