These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test

conditions, see the electrical characteristics.

(2)

Human body model, 1.5 k

Ω in series with 100 pF. The output pins of the two comparators (pin 1 and pin 7) have an ESD tolerance of

1.5 kV. All other pins have an ESD tolerance of 2 kV.

(3)

Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.

(4)

Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in

exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long term may adversely

affect reliability.

(5)

Do not short circuit output to V+, when V+ is > 12V or reliability will be adversely affected.

(6)

The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient

temperature is PD = (TJ(MAX) – TA)/θJA. All numbers apply for packages soldered directly into a PC board.
