+Serial (SPI) Tri-Color LED Driver
+
+![NLSF595](wokwi-nlsf595.svg)
+
+Use the NLSF595 shift register to connect power-hungry RGB LEDs to your microcontroller. A single unit can control two RGB LEDs, and a chain of two units can control up to five RGB LEDs.
+
+## Pin names
+
+| Pin   | Description                                            |
+| ----- | ------------------------------------------------------ |
+| SI    | Serial input                                           |
+| SCK   | Serial clock                                           |
+| RCK   | Storage (latch) pin                                    |
+| OE    | Output enable, active low. Connect to GND if not used. |
+| QA…QH | Parallel output                                        |
+| SQH   | Serial output\*                                        |
+| SCLR  | Reset (clear), active low. Connect to VCC if not used  |
+| GND   | Ground                                                 |
+| VCC   | Supply voltage                                         |
+
+\* Use the Q7S to chain multiple NLSF595 units together. Connect SQH to the SI pin of the next NLSF595 chip in chain.
+
+## Using the NLSF595
+
+You will need to connect at least 3 pins to your microcontroller: SI, SCK, and RCK.
+
+The OE pin can be used to disable the output of the shift register. If you need that functionality,
+connect it to your microcontroller. Otherwise, connect it to the ground to permanently enable the output.
+
+The output pins of the shift register, QA through QH, are usually connected to the input pins of common-anode [RGB LEDs](wokwi-rgb-led).
