Pin Definitions and Functions
Pin
Symbol Function
1, 2, 19, 13 N.C.
Not connected
3
QRES
Reset output; open-collector output connected to the
output via a resistor of 30 kΩ.
4-7,
14-17
GND
Ground
9
DRES
Reset delay; connected to ground with a capacitor.
10
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.
11
W
Watchdog; positive edge triggered input for monitoring a
microcontroller.
12
V_Q
5-V output voltage; block to ground with a 22−µF
capacitor.
18
V_I
Input voltage; block to ground directly at the IC with a
ceramic capacitor.
20
INH
Inhibit; TTL-compatible, low-active input.
