Pin Function
High Threshold Input. HTH and LTH monitor external voltages.
Ground.
Low Threshold Input. LTH and HTH monitor external voltages.
(“H” Version) Active-Low Push-Pull Output. OUT asserts low when VLTH <
VREF. OUT remains low until VHTH > VREF.
(“L” Version) Active-High Push-Pull output. OUT asserts high when VLTL <
VREF. OUT remains high until VHTH > VREF.
(“N” Version) Active-Low, Open-Drain Output. OUT asserts low when VLTH <
VREF. OUT remains low until VHTH > VREF.
