Control up to 170 3-color or 128 4-color Addressable LEDs
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.
It is available in Industrial (–40 °C to +85 °C) and Extended (–40 °C to +125 °C) temperature ranges. Smaller package options are available, contact sales for details.
