1 _{VDDx = VDD1 or VDD2.}
2 _{VINPUT is the input voltage of any of the MCLK, MSS, MO, SO, VIA, VIB, VIC pins.}
3 _{IOUTPUT is the output current of any of the SCLK, SSS, MI, SI, VOA, VOB, VOC pins.}
4 _{|CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining output voltages within the VOH and VOL limits. The common-mode}
voltage slew rates apply to both rising and falling common-mode voltage edges.
