Overview

The SN74LVC1G125DBVR is a single-channel, non-inverting buffer with a 3-state output designed for 1.65V to 5.5V operation. This logic gate features an active-low output-enable (OE) input, allowing the bus line to be effectively isolated when the buffer is disabled. It is a versatile component for signal buffering, bus isolation, and level shifting in mixed-voltage systems.

Why Choose This Part

This buffer provides high-drive capability of 32mA and features overvoltage-tolerant inputs, allowing it to safely interface with 5.5V signals even when powered at lower supply voltages. Its near-zero static supply current makes it ideal for power-sensitive battery-operated designs, while the SOT-23-5 package offers a small footprint for high-density layouts.

Applications

Bus Isolation
Disconnects downstream components from a shared bus to prevent loading or signal interference when the peripheral is inactive.
Voltage Level Translation
Bridging signals between different logic levels, such as shifting a 1.8V control signal to a 3.3V or 5V logic domain.
GPIO Current Boosting
Providing up to 32mA of drive current to handle heavy capacitive loads or LEDs that exceed a microcontroller's native I/O capabilities.
Signal Integrity Improvement
Used as a repeater to sharpen pulse edges and restore logic levels over long PCB traces or ribbon cables.

Getting Started

To use this part, connect VCC to your system rail (1.65V to 5.5V) and decouple with a 0.1uF ceramic capacitor. Drive the OE pin low to enable the buffer output, or pull it high to put the output into a high-impedance state. Ensure the input signal does not exceed 5.5V, regardless of the VCC supply voltage.
