Overview

The SN74LVC126APWR is a quadruple non-inverting bus buffer with 3-state outputs designed for 1.65V to 3.6V VCC operation. Each of the four independent gates is enabled by a high-level signal on its respective output-enable input, allowing the outputs to be placed in a high-impedance state for shared bus architectures.

Why Choose This Part

This buffer features 5.5V tolerant inputs regardless of the supply voltage, making it ideal for mixed-voltage systems. It offers high output drive capability of 24mA and a wide operating temperature range from -40C to 125C, suitable for industrial environments.

Applications

Level Shifting
Utilizing the 5.5V tolerant inputs to translate signals from 5V down to 3.3V or lower logic levels.
Bus Isolation
Isolating multiple peripherals on a shared SPI or parallel bus using the independent 3-state output controls.
Digital Signal Driving
Providing up to 24mA of drive current for high-speed digital signals across PCBs or short cables.

Getting Started

Ensure a 0.1uF ceramic decoupling capacitor is placed close to the VCC pin (Pin 14). When prototyping, use a TSSOP-14 to DIP breakout board or integrate directly into your PCB design using standard 0.65mm pitch footprints.
