VINPUT = VDDx, VCM = 1000 V,

transient magnitude = 800 V

1

VDDx = VDD1 or VDD2.

2

VINPUT is the input voltage of any of the MCLK, MSS, MO, SO, SSA0, or SSA1 pins.

3

IOUTPUT is the output current of any of the SCLK, MI, SI, SS0, SS1, SS2, or SS3 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.
