DESCRIPTION

NAME

1

GND

—

Ground pin. This pin must be connected to ground with a low-impedance connection.

2

RESET

O

RESET pin. RESET is an active low signal, asserting when VDD is below the threshold

voltage. When VDD rises above VIT, there is a delay time (td) until RESET deasserts.

RESET is a push-pull output stage.

3

VDD

I

Supply voltage pin. A 0.1-µF ceramic capacitor from this pin to ground is recommended to

improve stability of the threshold voltage.
