1

VDDx = VDD1 or VDD2.

2

VINPUT is the input voltage of any of the MCLK, MSS, MO, SO, VIA, VIB, or 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.
