Overview
The SN74ABT126D, produced by Texas Instruments, is a quadruple bus buffer gate with 3-state outputs. This device features independent line drivers, each with a 3-state output that can be disabled by a low signal on the associated output-enable (OE) input. The SN74ABT126D is designed for use in a variety of digital systems where bus buffering and signal isolation are necessary. It operates over a temperature range of -40°C to 85°C, making it suitable for a wide range of applications.
