Overview
The NLSX4373DR2G, produced by onsemi, is a 2-bit configurable dual-supply bidirectional auto-sensing translator. This device does not require a directional control pin and is designed to translate voltage logic signals between two different power supply rails, VCC and VL. The VCC and VL supply rails are configurable from 1.5 V to 5.5 V, allowing for the translation of logic signals to lower, higher, or equal value voltage levels on either side. The NLSX4373 is particularly suited for open-drain applications, such as the I2C communication bus.
