N.C.

Not connected

3QRES

Reset output; open-collector output connected to the

output via a resistor of 30 k

Ω.

4-7,

14-17

GND

Ground

DRES

Reset delay; connected to ground with a capacitor.

SRES

Reset threshold; for setting the switching threshold

connect with a voltage divider from output to ground. If this

input is connected to GND, reset is triggered at an output

voltage of 4.5 V.

Watchdog; positive edge triggered input for monitoring a

microcontroller.

5-V output voltage; block to ground with a 22

−µF

capacitor.

Input voltage; block to ground directly at the IC with a

ceramic capacitor.

INH

Inhibit; TTL-compatible, low-active input.
