DESCRIPTION/ORDERING INFORMATION  
This 7-bit LED dimmer for the two-line bidirectional bus (I2C) is designed to control (or dim) LEDs via the I2C  
interface [serial clock (SCL), serial data (SDA)]. Without this device, the microprocessor or microcontroller must  
be actively involved in turning on and off the LEDs (per the required dimming rate), which uses valuable  
processor time and the overloads I2C bus. The TCA6507 alleviates this issue by limiting the number of  
operations required by the processor in blinking LEDs and, thus, helps to create a more efficient system.
