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.

(1)

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 specified specifications and test conditions,

see the Electrical Characteristics tables.

(2)

Human Body Model is 1.5 k

Ω in series with 100 pF. Machine Model is 0Ω in series with 200 pF.

(3)

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 onto a PC board.

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 specified specifications and test conditions,

see the Electrical Characteristics tables.

(2)

Programming temperature range 0°C to 70°C .

(3)

When AVDD is in the voltage range of 4.5V to 13V, the supply voltage VDD can be in 2.25V to 3.6V range. When AVDD is in the voltage

range from 13V to 18V, the supply voltage VDD is limited to the 2.6V to 3.6V range

(4)

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 onto a PC board.
