1 1 GND Ground
2 — RESET
Active-Low Reset Output. RESET remains low while V
CC
is below the reset
threshold and for at least 100ms after V
CC
rises above the reset threshold.
RESET is open-drain on the MAX6328/MAX6348 and push-pull on the
MAX6326/MAX6346.
— 2 RESET
Active-High Reset Output. RESET remains high while V
CC
is below the reset
threshold and for at least 100ms after V
CC
rises above the reset threshold.
