Overview
The NLSX4373MUTAG is a 2-bit configurable dual-supply bidirectional auto-sensing level translator produced by onsemi. This device is designed to translate voltage logic signals between two different power supply rails, VCC and VL, without the need for a directional control pin. It supports a wide operating voltage range from 1.5 V to 5.5 V for both VCC and VL, making it versatile for various applications. The NLSX4373MUTAG is particularly suited for open-drain applications such as I2C and SMBus communication buses.
