False Triggers May Occur Under Certain Conditions

False triggers may occur on falling input pin:
  • If the slew rate on the input signal is greater than 2 V/µs for common-mode voltage below 0.5V
  • If the slew rate on the input signal is greater than 10 V/µs for common-mode voltage above 0.5V
  • If the slew rate on the input signal is greater than 10 V/µs for any common-mode voltage and Low-Power mode is enabled

Work around

None.
