(1)

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

(2)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test condition which ensure specific performance limits. This assumes that the device is within the

Operating Ratings. Specifications are not ensured for parameters where no limit is given. However, the typical value is a good indication

of device's performance.

(3)

Typical specifications are measured at 25°C and represent the parametric norm.

(4)

Tested limits are specified to AOQL (Average Outgoing Quality Level).

(5)

Datasheet min/max specification limits are specified by design, test, or statistical analysis.

(6)

PCB layout will affect cross talk. It is recommended that input and output traces be separated by as much distance as possible. Return

ground traces from outputs should be independent back to a single ground point and use as wide of traces as possible.
