PCA9621
65 mA 8-bit 2-wire bus output port
11. Application information
Figure 11 shows the PCA9621 in conjunction with the PCA9646 bus multiplexer in a LED
drive application. Each PCA9621 can drive 8 LEDs, and using the address pins on the IC,
up to 8 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’s in series (refer to the PCA9646 data sheet), the structure may be further
extensively multiplied into a huge array.
