CMTI is the capability of the device to tolerate a rising or falling voltage step on the input without coupling significant disturbance on the output signal. The device is specified for the maximum common-mode transition rate when the output signal does not experience a disturbance greater than 200mV lasting longer than 1µs, as shown in Figure 7-3 with a 150kV/µs common-mode input step. Higher edge rates than the specified CMTI can be supported with sufficient filtering or blanking time after common-mode transitions.
