WARNING:Operations at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
Notes: 1. Referenced to RGND1,RGND2,TGND1,TGND2,AGND,DGND at 0V.
2. Transient currents of up to 100 mA will not cause SCR latch-up.

Notes: 3. TV+1,TV+2,AV+,DV+,RV+1,RV+2 should be connected together.TGND1,TGND2,RGND1,
RGND2,DGND1,DGND2,DGND3 should be connected together.
4. Power consumption while driving line load over operating temperature range. lncludes IC and load.
Digital input levels are within 10% of the supply rails and digital outputs are driving a 50 pF
capacitive load.
5. Assumes 100% ones density and maximum line length at 3.465V.
6. Assumes 50% ones density and 300ft. line length at 3.3V.
