Note: 1. The RST terminal is connected to an internal 100 kΩ pull-up resistor. When this terminal is not used, connect a 0.1 μF capacitor between
the terminal and ground to prevent misoperation at power-on.
2. Connect the CAP terminal to a capacitor for smoothing power supply. Connect a 0.1 μF capacitor between the terminal and GND.
3. Always leave the TST1 and TST2 terminals open.
4. Leave unused output terminals open.
