SYMBOL
DESCRIPTION
1
WD
Clock input pin for watchdog timer. If this IC is only used as a power-on reset timer, this
pin is connected to RST1 .
2
TC
Time setting pin for the reset and watchdog timers. R1 leads to VCC, and C1 leads to
GND.
3
RST1
Supplies an NPN transistor open-collector output.
● Generates a reset signal determined by the CR combination connected to the TC pin.
● Supplies reset pulses intermittently if no clock is given to the WD pin.
4
GND
Grounded
5
6
ADJ
VCC detect voltage (1) adjusting pin. The detection voltage is 4.6V when this pin is
grounded ; it is 3.5V when this pin is directly connected to VCC.
6
7
VCC
Power supply pin for internal circuit. The output voltage can also be detected at this pin.
7
8
RST2
Supplies an NPN transistor open-collector output. It is the output pin for VCC detect
voltage (2) . The detect voltage has a hysteresis of 0.17V.

5
NC
Not connected pin.(Electrically,this pin is completely open.)
