*1 Channel-to-channel skew is defined as the ratio between (any Iout – average Iout) and average Iout, where average
Iout = (Imax + Imin) / 2.
*2 Chip-to-Chip skew is defined as the range into which any output current of any IC falls.
*3 To operate driver within supply voltage 6.5V~8.5V may drop the output current due to semiconductor process
variations.
*4 IO excluded.
