(1)
All voltages are measured with respect to the ground pin, 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 conditions 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 specified at 25°C and represent the parametric norm.
(4)
Tested limits are specified to TI's AOQL (Average Outgoing Quality Level).
(5)
Datasheet min/max specification limits are specified by designs, test, or statistical analysis.
(6)
The shutdown pin (pin1) should be driven as close as possible to VDD for minimum current in Shutdown Mode.
