DC Electrical Characteristics*
* Supply voltage and operating temperature are as per Recommended Operating Conditions.
* Voltages are with respect to ground (GND) unless otherwise stated.
AC Electrical Characteristics* - Timing Parameter Measurement Voltage Levels (see Figure 25).
* Supply voltage and operating temperature are as per Recommended Operating Conditions.
* Voltages are with respect to ground (GND) unless otherwise stated.
AC Electrical Characteristics* - Input timing for REF0, REF1 and REF2 references (see Figure 26).
* Supply voltage and operating temperature are as per Recommended Operating Conditions.
* Period Min/Max values are the limits to avoid a single-cycle fault detection. Short-term and long-term average periods must be within
Out-of-Range limits.
