TIMING DIAGRAMS
Note 5: Not 100% Production tested. Guaranteed by Design and/or Characterization.
Note 6: All electrical parameters are guaranteed to function over the stated VDD, VCS and temperature range. Electrical parameters not specified as
"guaranteed by design" are tested with a VDD voltage required of the specific application. For example, if the device is to be operated at 3.3V and VCS
supply of 12V, it is tested with a VDD supply of 3.3V, +-10% and a VCS supply of 12V, +-10%.
