... APPLICATIONS INFORMATION Negative going V transients CC The ZXCM209/210 are good degree, immune to short duration negative going supply transients. Under certain circumstances very brief transients are allowed without inappropriate false triggering of the reset circuit. The response to supply transients is shown in the Noise Immunity graph in the typical characteristics. The ...
