... NXP Semiconductors 11. Application information Figure 11 drive application. Each PCA9621 can drive 8 LEDs, and using the address pins on the IC uniquely addressed devices can sit on one bus branch. The PCA9646 has four such outputs, giving 256 LEDs in the structure shown. By additionally using the address pins on the PCA9646, the entire structure may be repeated 8 times, allowing 2048 LEDs to be uniquely driven. By additionally placing PCA9646’ ...
