It would seem there is a severe lack of TLC5940 DIP ICs in the market causing a backorder for months at all major suppliers. This is our attempt to provide a replacement as close to the TLC5940NT as possible.
Although the two ICs are identical, for some reason TI decided to give the SMT part a different pinout. Therefore, this item will not work for those who have circuit boards made based on the TLC5940NT (but will in all other situations).
The TLC5940 is a 16-channel, constant-current sink LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step, constant-current sink (dot correction). The dot correction adjusts the brightness variations between LED channels and other LED drivers. The dot correction data is stored in an integrated EEPROM. Both grayscale control and dot correction are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels.
The TLC5940 features two error information circuits. The LED open detection (LOD) indicates a broken or disconnected LED at an output terminal. The thermal error flag (TEF) indicates an overtemperature condition.
