(1) The analog inputs are protected as shown below. Input voltage magnitudes beyond the Absolute Maximum Ratings may damage this device.

(2) The maximum clock frequency for non-demux mode is 1 GHz.

(3) Typical figures are at T_A = 25°C, and represent most likely parametric norms. Test limits are ensured to Texas Instrument's average outgoing quality level (AOQL).

(4) This parameter is specified by design and/or characterization and is not tested in production.
