TLC5920 16x8 BIT LED DRIVER/CONTROLLER SLAS264A – MARCH 2000 REVISED SEPTEMBER 2002 D D D D D D D D D D Drive Capability: – Segment . . . 30 mA × 16 Bits – Common . . . 640 mA Constant Current Output . . . 3 mA to 30 mA (Current Value Setting for All Channels Using External Resistor) Constant Current Accuracy ±6% (Maximum Error Between Bits) Data Input: Clock Synchronized Serial Input LED Type Applied Cathode Common Logic Power Supply Voltage 4.5 V to 5.5 V LED Power Supply Voltage 4.5 V to 5.5 V Operating Frequency . . . 10 MHz Operating Free-Air Temperature Range –20°C to 85°C 48-Pin SSOL Package description The TLC5920 is an LED driver incorporating a 16-channel shift register, data latch, and constant current circuitry with current value control and 8-channel common driver into a single chip. The constant output current is capable of 30 mA for 16 bits simultaneously, and the current value can be set by one external register. This device also includes a 16-bit segment driver and 8-bit common driver; therefore, the monocolor LED array with 16 × 8 dots can be driven by only one TLC5920, and a two-color LED array with 16 x 16 dots can be driven by two TLC5920s.
