ELECTRICAL CHARACTERISTICS

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: See “Propagation Delays” in the Operations section for a

capacitance.

Note 3: Determined by design, not tested in production.

Note 6: All currents into pins are positive; all voltages are referenced to

GND unless otherwise specified.
