TLC5920 16x8 BIT LED DRIVER/CONTROLLER is a LED driver produced by Texas Instruments. It integrates a 16-channel shift register, data latch, constant current circuit, current value control and 8-channel common driver into a single chip. This device can drive a 16×8 dot monochrome LED array or two 16×16 dot double color LED arrays.
The TLC5920 is a 16‑x‑8‑bit LED driver/controller that integrates a 16‑channel shift register, constant‑current output circuitry, and an 8‑bit common driver. It can drive a monochrome 16 × 8 LED matrix or two 16 × 16 matrices with two devices.
Key specifications include 4.5 V‑5.5 V supply ranges for logic, LED and analog rails, up to 30 mA per channel (640 mA total), 10 MHz maximum operating frequency, and operation from –20 °C to 85 °C. The device is offered in a 48‑pin SSOP DL package with various RoHS‑compliant options.
