6276 LED Driver

The 6276 LED driver is useful for controlling multiple LEDs. It extends the output of the microprocessor.

Changed lines 19-20 from:

One difference you will notice is that the output pin of the chip connects to the ground leg (Cathode) of the LED. The power leg of the LED is connected to a power source. This is called "sinking" the LED.

6276 LED Driver Here are the parts you will need:

The 6276 LED driver is a shift register capable of handling the milliamps required to drive an LED. It is controlled digitally through four wires from a microcontroller.

One difference you will notice is that the output pin of the chip connects to the ground leg (Cathode) of the LED. The power leg of the LED is connected to a power source. This is called "sinking" the LED.

Pin Description:

  • SDI - Serial Data input
  • CLK - Serial clock input
  • LE - Latch Enable
  • OE - Output Enable
  • SDO - Serial Data output. This is used for cascading multiple 6276 drivers
  • Rext - Connect a resistor to this pin from ground. 220 ohm is a good start
  • +5 - Logic Supply
  • GND - Ground
  • OUT15 - OUT0 - Outputs, connect LED ground to selected pin
