What are the key features of 74LVC1G125DBVT?
- Wide supply voltage range of 1.65V to 5.5V enables direct interfacing between 1.8V, 2.5V, 3.3V, and 5V logic domains without external level-shift circuitry
- 3-state output with active-low output enable allows multiple drivers to share a common bus without contention in bi-directional and multiplexed signal architectures
- LVC logic family in a compact 5-pin SOT-23 package delivers 24mA output drive current for reliable bus line driving in space-constrained PCB designs
What is 74LVC1G125DBVT used for?
The 74LVC1G125DBVT is used in mixed-voltage digital systems for isolating bus segments, buffering microcontroller GPIOs driving capacitive loads, and enabling tri-state bus sharing in SPI, UART, and I²C arbitration circuits. Its 1.65V to 5.5V supply range makes it an ideal interface between 3.3V microcontrollers and 5V peripheral buses without external level shifting. The compact SOT-23-5 footprint suits wearable devices, sensor interface boards, and any design where a single-channel line driver must occupy under 5mm² of board area.

Frequently Asked Questions
What supply voltage range does 74LVC1G125DBVT support for mixed-logic interfacing?
The 74LVC1G125DBVT operates from 1.65V to 5.5V, covering all common logic supply levels including 1.8V, 2.5V, 3.3V, and 5V. This broad range allows it to buffer signals between a 3.3V MCU GPIO and a 5V bus without any additional level-shift components, simplifying BOM in multi-voltage board designs.
How does the 3-state output of 74LVC1G125DBVT support shared bus topologies?
When the active-low output enable pin is deasserted high, the output enters high-impedance (Hi-Z) state, effectively disconnecting the driver from the bus. Up to 64 LVC-family 3-state devices can share a single bus line without contention, enabling flexible multiplexed SPI, UART, or custom parallel bus architectures in embedded systems.
How much output drive current can 74LVC1G125DBVT deliver for capacitive bus loads?
The device sources and sinks up to 24mA of output current, sufficient to drive bus lines with up to 50pF parasitic capacitance at logic-compliant speeds. This drive strength is approximately 3x higher than a standard LVC GPIO output, making it suitable for buffering microcontroller pins that would otherwise struggle to meet rise-time requirements on loaded PCB traces.
Which 5-pin SOT-23 alternatives exist if 74LVC1G125DBVT is out of stock?
Pin-compatible alternatives in the same SOT-23-5 footprint include the SN74LVC1G125DBVR (tape and reel variant), Nexperia 74LVC1G125GW, and ON Semiconductor NC7SZ125P5X. All share the same 1.65V to 5.5V supply range, 24mA drive, and 3-state function, allowing direct PCB substitution without layout changes.
