## Description

## Description 

The IS3751 is a DMX512-to-addressable-LED protocol converter chip. It operates fully autonomously, requiring no microcontroller or processor, thereby reducing engineering costs and accelerating the product’s time-to-market.

It can control up to 170 3‑color or 128 4-color addressable LEDs at a refresh rate of 40 Hz. 

An RS485 receiver or transceiver converts the DMX differential signaling to TTL-compatible levels for the IS3751, which then directly generates data stream for the addressable LEDs. 

The chip includes a pin for selecting between 3-color and 4-color addressable LEDs, and a blinking indicator pin to show when a DMX signal is present.

The device operates at 3.3 V, with 5 V-tolerant open‑collector LEDs control pin and with 5 V-tolerant RX pin for DMX input, allowing compatibility with both 3.3 V and 5 V RS485 receivers or transceivers.
