Six-Channel Digital Isolator

INSULATION AND SAFETY CHARACTERISTICS

side A are referenced to GNDA. All voltages of side B are referenced to GNDB, unless otherwise noted.

Note 3: Guaranteed by design. Not production tested.

Note 4: The undervoltage lockout threshold and hysteresis guarantee that the outputs are in a known state during a slump in the

supplies. See the Detailed Description section for more information.

Note 5: The isolation is guaranteed for t = 60s, and tested at 120% of the guaranteed value for 1s.

the same I/O pin. This ensures that the I/O channels are not latched low when any of the I/O inputs are driven low (see the

Bidirectional Channels section).

Note 7: The common-mode transient immunity guarantees that the device will hold its outputs stable when the isolation voltage

changes at the specified rate.

Note 8: Pulse-width distortion is defined as the difference in propagation delay between low-to-high and high-to-low transitions

on the same channel. Channel-to-channel skew is defined as the difference in propagation delay between different chan-

nels on the same device. Part-to-part skew is defined as the difference in propagation delays (for unidirectional channels)

between different devices, when both devices operate with the same supply voltage, at the same temperature and have

identical package and test circuits.
