Overview
The NLVSX4373DR2G is a 2-Bit configurable dual-supply bidirectional auto sensing translator produced by onsemi. This component does not require a directional control pin and is designed to translate voltage logic signals between two different power supply rails, VCC and VL, which can be configured from 1.5V to 5.5V each. This flexibility allows for the translation of logic signals to lower, higher, or equal value voltage logic signals on either side. The NLVSX4373DR2G features open-drain outputs with integrated 10kΩ pullup resistors on the I/O lines, making it suitable for open-drain applications such as the I2C communication bus.
