Data Transmission Method

Note: D1 is the data from MCU, and D2, D3, D4 are from Cascade Circuits.

Composition of 24bit data

Note: Data transmit in order of GRB, high bit data is first.

Typical application circuit

Remarks: Rx is the IC’s protective resistor, power spike and reverse connection of the battery power terminal, will be

protected, its range of 100R~300R. VCC & VDD are connected together without use of protective resistors. C1 is

external filter capacitor, its value of 100NF. The LED also works without the external filter capacitor because it has filter

capacitor built-inside.
