Absolute Maximum Ratings
Absolute maximum ratings are those values which damage to the device may occur. Functional operation under these
conditions or at any other condition beyond those indicated in the operational sections of this specification is not
implied.

Power Supply Operating Requirements
SAA7780 Minimum VDD Operating Requirement
IMPORTANT: The SAA7780 requires VDD >= 3.0V. If VDD < 3.0V, excessive damage from hot electrons might occur.
SAA7780 Power Supply Sequencing Requirement
0 <= (NWELL - VDD) < 4.0V
IMPORTANT: The 5.0V (NWELL) supply must power up ahead of the 3.3V (VDD, not VDDIC) supply. Likewise, the
3.0V supply must power down before the 5.0V supply. More specifically, the voltage level of the 5.0V supply must
always exceed, or at least equal, the voltage level of the 3.3V supply during power up or down, but not by more than
4.0V. This is due the biasing of the P+ source junctions and that some pad gate oxides see the (NWELL-VDD) voltage
level. If this level exceeds 4.0V or becomes less than 0V, damage will occur.
Device Maximum Ratings
The following table notes both the operating and non-operating conditions for both the 3.0V and 5.0V tolerant pads.
Remember that the ranges imply an operating range unless otherwise noted. The 5.0V tolerant pads signal at 3.0V
levels and are CMOS and TTL compatible.
