1. See Figure 3 for details, Hysteresis=VTRIP- - VTRIP+.

2. Specified by design.

3. VID is the differential voltage present at the comparator inputs.

4. Open-drain output can be pulled up to 2.7~18 V range, regardless of VCC.

5. The comparator response time specified is the time interval between the input step and the instant when the output crosses 1.4 V.

6. The RESET input has an internal 2 MΩ (typical) pull-down. In case RESET pin is left open, the output

shows a LOW state, with

transparent comparator operation.
