(1)

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may

degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond

those specified is not implied.

(2)

The algebraic convention, whereby the most negative value is a minimum and the most positive value is a maximum

(3)

All voltages are with respect to ground, unless otherwise specified.

(4)

The package thermal impedance is calculated in accordance with JESD 51-7.

ANALOG SPECIFICATIONS

Typical Values are specified at VDD=5V and operating temperature of 25 C
