1 Features
• Eight LED Drivers (Each Output Programmable at
OFF, ON, Programmable LED Brightness,
Programmable Group Dimming/Blinking Mixed
With Individual LED Brightness)
• Eight Open-Drain Output Channels
• 256-Step (8-Bit) Linear Programmable Brightness Per LED Output Varying From Fully Off (Default)
to Maximum Brightness Using a 97-kHz PWM
Signal
• 256-Step Group Brightness Control Allows
General Dimming [Using a 190-Hz PWM Signal
From Fully Off to Maximum Brightness (Default)]
• 256-Step Group Blinking With Frequency Programmable From 24 Hz to 10.73 s and Duty
Cycle From 0% to 99.6%
• 64 Programmable Slave Addresses Using Three
Hardware Address Pins
• Four Software Programmable I2C Bus Addresses
(One LED Group Call Address and Three LED
Sub Call Addresses) Allow Groups of Devices to
be Simultaneously Addressed Any Combination
(For Example, One Register Used for ‘All Call’ so
That All the TLC59208Fs on the I2C Bus Can be
Simultaneously Addressed and the Second
Register Used for Three Different Addresses so
That One Third of All Devices on the Bus Can be
Simultaneously Addressed)
• Software Enable and Disable for I2C Bus Address

3 Description
The TLC59208F is an I2C bus controlled 8-bit LED
driver optimized for red/green/blue/amber (RGBA)
color mixing applications. Each LED output has its
own 8-bit resolution (256 steps) fixed frequency
individual PWM controller that operates at 97 kHz
with a duty cycle that is adjustable from 0% to 99.6%
to allow the LED to be set to a specific brightness
value.
