What are the key features of SN74LV125ADGVR?
- Quad 3-state bus buffer with active-low enable enables four independent channels of bus isolation and signal driving
- LV/LV-A logic family supports 1.65V to 5.5V supply range for multi-voltage level interfacing in mixed-logic systems
- 16mA (IOL) output sink current capability drives standard CMOS and TTL-compatible bus loads reliably
- Pb-free 14-pin SOIC tape-and-reel (DGVR) packaging supports automated high-volume surface-mount assembly
What is SN74LV125ADGVR used for?
The SN74LV125ADGVR is used for signal buffering, bus isolation, and logic-level interfacing in microcontroller-based systems, memory bus drivers, and communication interface circuits where low-voltage 3-state buffer operation is needed. It is well suited for SPI, I2C, and parallel bus expansion in IoT devices, embedded systems, and consumer electronics operating from 1.8V to 5V supplies. Engineers also deploy it in PCB bus arbitration and voltage-level shifting applications requiring independent enable control for each of the four buffer channels.

Frequently Asked Questions
What are the key specifications of the SN74LV125ADGVR?
The SN74LV125ADGVR is a quad 3-state bus buffer in the LV/LV-A logic family, with active-low enable (OE), unidirectional signal flow, 16mA maximum output low current (IOL), 50pF load capacitance, and a 14-pin SOIC package. It is Pb-free (JESD-609 e4) and supports supply voltages from 1.65V to 5.5V.
What does the active-low enable (OE) pin do on the SN74LV125ADGVR?
Each of the four buffer channels on the SN74LV125ADGVR has an independent active-low output enable (OE) pin. When OE is pulled low, the corresponding buffer output follows its input; when OE is high, the output is placed in a high-impedance (3-state) mode, effectively disconnecting the buffer from the bus and preventing bus contention.
What supply voltage range does the SN74LV125ADGVR support?
The SN74LV125ADGVR operates from a supply voltage range of 1.65V to 5.5V, making it compatible with 1.8V, 2.5V, 3.3V, and 5V digital logic systems. This wide range is especially useful for voltage-level translation and interfacing between mixed-voltage subsystems in modern embedded and IoT designs.
What applications is the SN74LV125ADGVR suitable for?
This device is ideal for bus buffering, signal isolation, parallel data bus driving, SPI and I2C bus expansion, and processor-to-peripheral interfacing in low-voltage digital systems. Its quad-channel 3-state architecture and wide supply voltage range make it a versatile choice for consumer electronics, industrial controllers, microcontroller expansion boards, and communication interface designs.
