6.3.2.3 Common Mode Transient Immunity (CMTI)

CMTI is the capability of the device to tolerate a rising or falling voltage step on the high-voltage pins without coupling a significant disturbance to the output signal. The ISOTMP35R device is specified for the maximum common-mode transition rate under which the output signal does not experience a disturbance greater than 200mV lasting longer than 4µs, as shown in Figure 6-2 with a 65.8kV/µs common-mode input step. Higher edge rates than the specified CMTI can be supported with sufficient blanking time after common-mode transitions.
