Instructions for Use:

1. Power Supply Connection:

   • Connect the positive supply voltage (VDD) and negative supply voltage (VSS) as specified in the operating voltage range.
   • Ensure proper decoupling capacitors are placed close to the power pins to minimize noise.

2. Serial Data Input:

   • The serial data input (SDI) should be connected to a microcontroller or another data source that can provide data at up to 10MHz.
   • Load the data into the internal shift register using the serial data input pin.

3. Shift Register Clock (SRCLK):

   • Apply clock pulses to the SRCLK pin to shift data into the device.
   • Each rising edge of the SRCLK signal shifts the data one position within the shift register.

4. Latch Enable (LE):

   • After all data is shifted into the shift register, apply a high pulse to the LE pin to transfer the data from the shift register to the latch.
   • This action updates the output drivers with new data.

5. Output Enable (OE):

   • Control the output enable pin to turn on or off all outputs simultaneously.
   • Setting OE low enables the outputs; setting it high disables them.

6. Connecting Outputs:

   • Connect each output pin to the corresponding load (e.g., LEDs, display segments).
   • Ensure the current through each output does not exceed ±30mA to prevent damage.

7. Handling and Storage:

   • Handle the IC with care to avoid static damage.
   • Store in a temperature-controlled environment within the storage temperature range to maintain reliability.
