Pin Definitions and Functions

Pin

Symbol

Function

1INH

Inhibit; TTL-compatible, low-active input

2QRES

Reset output; open-collector output internally connected to

the output via a resistor of 30 k

Ω.

4-7, 14-17

GND

Ground

9DRES

Reset delay; connected to ground by a capacitor

10

SRES

Reset threshold; for setting the switching threshold connect

by 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.

11

V

Q

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

−µF capacitor.

20

V

I

Input voltage; block to ground directly at the IC by a ceramic

capacitor.
