Instructions for Use

1. Power Supply Connection:

   • Connect VCC to the positive terminal of the power supply.
   • Connect GND to the negative terminal of the power supply.

2. Data Input:

   • Connect the data input pin (DIN) to the output of the RF receiver or other data source.

3. Address Setting:

   • Set the address pins (A0-A7) to match the address of the corresponding encoder (PT2262).
   • Address pins can be set to either high (VCC) or low (GND).

4. Output Configuration:

   • The four output channels (OUT1-OUT4) are open collector outputs. Connect pull-up resistors (typically 1k惟 to 10k惟) between each output and VCC.
   • When a valid code is received and decoded, the corresponding output will be pulled low.

5. Reset Function:

   • The reset pin (RST) can be used to clear the decoder. Connect it to GND for normal operation or to VCC to reset the decoder.

6. Enable Pin:

   • The enable pin (EN) can be used to disable the decoder. Connect it to GND to enable the decoder or to VCC to disable it.

7. Testing:

   • Ensure all connections are correct before applying power.
   • Test the decoder by sending a valid code from the encoder and verifying that the corresponding output is activated.

8. Handling:

   • Handle the IC with care to avoid static damage.
   • Store in a dry environment to prevent moisture damage.
