Overview
The CLVC126AQPWRG4Q1, part of the SN74LVC126A-Q1 series from Texas Instruments, is a quadruple bus buffer gate designed for automotive and other high-reliability applications. This device operates within a voltage range of 1.65V to 3.6V, making it versatile for various system environments. It features 3-state outputs, which can be disabled when the associated output-enable (OE) input is low, ensuring high-impedance states during power-up or power-down. The SN74LVC126A-Q1 is also capable of translating signals between 3.3V and 5V devices, making it suitable for mixed-voltage systems.
