NOTES:

10. The Tri-Level Inputs internal switching thresholds are approximately 0.43V and 1.34V. It is advised to float the inputs or tie to ground or AVDD,

depending on desired function.

11. The voltage is expressed in peak-to-peak differential swing. The peak-to-peak singled-ended swing is one-half of the differential swing.
