Overview
The SN74LVC2G126DCURG4, produced by Texas Instruments, is a dual bus buffer/line driver with 3-state outputs. This device is designed for operation over a wide range of supply voltages, from 1.65 V to 5.5 V, making it versatile for various applications. It features high-drive CMOS technology, enabling it to drive multiple outputs and support high-speed applications up to 100 MHz. The inputs are 5.5-V tolerant, allowing the device to translate down to the VCC level, which is beneficial for interfacing with different voltage levels.
