(1)

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

(2)

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

is functional, but do not specify specific performance limits. Electrical Characteristics state DC and AC electrical specifications under

particular test conditions which ensure specific performance limits. This assumes that the device is within the Operating Ratings.

Specifications are not specified for parameters where no limit is given, however, the typical value is a good indication of device

performance.

(3)

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

(4)

Limits are ensured to TI's AOQL (Average Outgoing Quality Level).
