Operating Ratings
(1)
Supply Voltage 4V ≤ V
IN
≤ 14V
(1) Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which
the device is intended to be functional, but device parameter specifications may not be ensured under these conditions. For
specifications and test conditions, see the Electrical Characteristics.
