Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: All currents into pins are positive; all voltages are referenced to

GND unless otherwise noted.

Note 3: VCC maximum pin voltage is limited by input current. Since the

VCC pin has an internal 6.5V shunt regulator, a low impedance supply that

exceeds 6V may exceed the rated terminal current. Operation from higher

voltage supplies requires a series dropping resistor. See Applications

Information.

Note 4: Guaranteed by design, not subject to test.
