NOTES:
9. The Tri-Level Inputs internal switching thresholds are approximately. 0.43V and 1.34V. It is advised to float the inputs, tie to ground or AVDD depending
on desired function.
10. The voltage is expressed in peak-to-peak differential swing. The peak-to-peak singled-ended swing is 1/2 of the differential swing.
Digital Specifications Boldface limits apply over the operating temperature range, -40°C to +85°C. (Continued)
