• Eight LED Drivers (Each Output Programmable At Off, On, Programmable LED Brightness, Programmable Group Dimming/Blinking Mixed With Individual LED Brightness
• Eight Constant-Current 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 24Hz to 10.73s and Duty Cycle From 0% to 99.6%
• Four Hardware Address Pins Allow 14 TLC59108 Devices to be Connected to the Same I2C Bus
• Four Software-Programmable I2C Bus Addresses (One LED Group Call Address and Three LED Sub Call Addresses) Allow Groups of Devices to be Addressed at the Same Time in Any Combination. For Example, One Register Used for All Call, so That All the TLC59108 Devices on the I2C Bus Can be Addressed at the Same Time, and the Second Register Can be Used for Three Different Addresses so That One-Third of All Devices on the Bus Can be Addressed at the Same Time in a Group.
