SN74ABT126DRG4 Quad Bus Buffer Gate by Texas Instruments

The SN74ABT126DRG4 is a high-performance, quad bus buffer gate designed and manufactured by Texas Instruments (TI), a leader in semiconductor solutions. This integrated circuit is part of the ABT family, which is known for its advanced bicmos technology and is tailored to address the needs of high-speed 5V tolerant systems.

The device features four independent non-inverting buffer gates with 3-state outputs. Each gate is equipped with a separate output-enable (OE) input, which allows the user to place the output in either a high-impedance state or a low-impedance state, making it ideal for bus-oriented applications. The SN74ABT126DRG4 is capable of driving heavily loaded outputs with up to 64 mA of continuous current and can handle transient currents of up to 300 mA, providing reliable performance for high-speed interfacing.

Designed with a standard SOIC-14 (DRG) package, the SN74ABT126DRG4 ensures a compact footprint on printed circuit boards (PCBs), which is beneficial for space-constrained applications. The device operates over a broad supply voltage range of 4.5V to 5.5V, which makes it compatible with typical 5V systems. Additionally, the SN74ABT126DRG4 is characterized for operation from -40°C to 85°C, ensuring stable performance across a wide range of environmental conditions.
