ISOLATION CHARACTERISTICS T

A = 25°C.

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: Guaranteed by design, not production tested.

Note 3: Guaranteed by other measured parameters and is not directly tested.

Note 4: Device considered a 2-terminal device. Measurement between

groups of pins A1 through C6 shorted together and pins N1 through R6

shorted together.

Note 5: The rated dielectric insulation voltage should not be interpreted as

a continuous voltage rating.

Note 6: In accordance with UL1577, each device is proof tested for the

6000VRMS rating by applying an RMS voltage multiplied by an acceleration

factor of 1.2 for one second.

Note 7: Evaluated by Design, not production tested.

Note 8: See Table 5 for minimum and maximum timing specifications

affected by the selection of SCK2 frequencies in the configuration register.

Note 9: All currents into device pins are positive; all currents out of device

are negative. All voltages are referenced to their corresponding ground

unless otherwise specified.

Note 10: See Table 2 for delay requirements between falling edge of BUSY

and SCK for large word lengths.

Note 11: Continuous operation above specified maximum operating

junction temperature may result in device degradation or failure.
