¹I_OXis the Channel x output current, where x is A, B, C, or D.

²V_IXHis the input side logic high.

³V_IXLis the input side logic low.

⁴|CM_H| is the maximum common-mode voltage slew rate that can be sustained while maintaining the voltage output (V_O) > 0.8 V_DDx. |CM_L| is the maximum common-mode voltage

slew rate that can be sustained while maintaining V^O> 0.8 V. The common-mode voltage slew rates apply to both the rising and falling common-mode voltage edges.
