SN74LVC1G125DBVR Single Bus Buffer with 3-State Output (SOT-23-5)

Ensure reliable signal transmission and logic level translation in your circuits with the SN74LVC1G125DBVR single bus buffer. Operating across a wide voltage range of 1.65V to 5.5V, this versatile logic gate is an essential component for isolating signals and driving data lines in modern digital electronics, flight controllers, and IoT devices.

A standout feature of this IC is its overvoltage-tolerant inputs, which allow it to safely accept 5V signals even when powered by a lower voltage (like 3.3V), making it an excellent one-way logic level shifter. Additionally, it features an active-low Output Enable (OE) pin, allowing the output to be placed into a high-impedance (3-state) mode when not in use. Packaged in a compact SOT-23-5 form factor, it is perfect for space-constrained PCB designs.

Key Features:

• Wide Operating Range: Functions seamlessly on supply voltages from 1.65V up to 5.5V.

• Overvoltage Tolerant: Inputs can safely handle 5V logic signals regardless of the supply voltage, ideal for level shifting.

• 3-State Output: The Output Enable (OE) pin allows the device to disconnect from the bus to prevent signal conflicts.

• High Drive Capability: Delivers strong signal output to drive long traces or LEDs (e.g., WS2812 data lines).
