Pin Description

Pin Number

Pin Name

Pin Function

NIC

No Internal Connection. A signal applied to this pin will have no effect

on device operation.

GND

Ground

INP

Input: Analog input to the comparator. When VINP > VREF+ VHYST, VOUT is

asserted, and the condition is held until VINP < VREF.

OUT

(“N” Version)

Output: Active-high, open-drain output. This output is low when

VINP < VREF, indicating a low voltage input. The output is high when

VINP > VREF + VHYST.

OUT

(“H” Version)

Output: Active-high, Push-pull output. This output is low when

VINP < VREF, indicating a low voltage condition. The output is high when

VINP > VREF+ VHYST.

OUT

(“L” Version)

Output: Active-low, Push-pull output. This output is high when

VINP < VREF, indicating a low voltage condition. The output is low when

VINP > VREF+ VHYST.

VDD

Power Supply (Input): Independent supply input for internal circuitry.
