Overview
The 74LVC126ADR2G is a high-performance, low-power, low-voltage quadruple bus buffer gate produced by onsemi. This device is designed to operate over a wide voltage range from 1.65V to 3.6V, making it versatile for various applications. It features independent line drivers with 3-state outputs, enabling each output to be disabled when the associated output-enable (OE) input is low. This component is particularly useful in mixed 3.3V and 5V system environments due to its 5.5V tolerant inputs and outputs.
