Overview
The SN74LVC1G126DBVT is a single bus buffer gate with 3-state output produced by Texas Instruments. This device is part of the LVC (Low-Voltage CMOS) family and is designed for operation over a wide voltage range from 1.65 V to 5.5 V. It features high-speed data acquisition and generation capabilities, making it suitable for various high-speed applications.
The device includes an output enable (OE) input that controls the state of the output, allowing it to be set to a high-impedance state when OE is low. This functionality is particularly useful in applications requiring output control and bus management.
