Symbol Function

1I

Input

block to ground directly at the IC with a ceramic capacitor

2RO

Reset Output

open collector output with integrated pull-up resistor;

optional external pull-up resistor of

≥ 10 kΩ to pin Q;

leave open if reset function not needed

3GND

Ground

internally connected to heat slug

4EN

Enable Input

high level input signal enables the IC;

low level input signal disables the IC;

integrated pull-down resistor

5Q

Output

block to ground with a capacitor close to the IC terminals, respecting the values given

for its capacitance and ESR in “Functional Range” on Page 6
