The device has built-in rejection of fast transients on the V_DD pin. The rejection of transients depends on both the duration and the amplitude of the transient. The amplitude of the transient is measured from the bottom of the transient to the negative threshold voltage of the device, as shown in Figure 9-1.

Figure 9-1 Voltage Transient Measurement

The device does not respond to transients that are fast duration and low amplitude or long duration and small amplitude. Transients meeting or longer than the t_w specified in the Section 7.6 section triggers a reset.
