*1 CMTI is tested by applying a pulse that rises and falls suddenly (VCM = 0.5 kV) between GND1 on the input side
and GND2 on the output side (pins 4 and 5) by using the circuit shown in Fig. 9 CMTI Test Circuit. CMTI is
defined at the point where the differential output voltage (VOUT+ − VOUT−) fluctuates 200 mV (>1 μs) or more from the
average output voltage.
*2 This is the value of the transient voltage at the differential output when 1 Vp-p, 1 MHz, and 40 ns rise/fall time
square wave is applied to both VDD1 and VDD2.
