Applications
The SN74HC125DR is widely used in microcontroller and FPGA systems to buffer and drive data buses, preventing signal degradation over long traces. It is ideal for bidirectional bus isolation, level shifting between logic domains, and driving multiple loads in industrial control, communication equipment, and consumer electronics. Its 3-state outputs enable shared-bus architectures where multiple devices must coexist on a single bus.

Frequently Asked Questions
What is the supply voltage range of the SN74HC125DR?
The SN74HC125DR operates from a supply voltage (VCC) range of 2V to 6V, making it compatible with both 3.3V and 5V logic systems. This wide range is characteristic of the HC CMOS family and allows flexible integration into mixed-voltage designs.
What are the typical applications for the SN74HC125DR?
The SN74HC125DR is commonly used as a bus buffer and line driver in microcontroller, FPGA, and DSP systems. Typical applications include data bus expansion, signal buffering on long PCB traces, bus isolation between voltage domains, and driving multiple logic inputs simultaneously in industrial, telecom, and consumer electronics equipment.
How does the output enable function work on the SN74HC125DR?
Each of the four buffers in the SN74HC125DR has an independent active-low output enable (OE) pin. When OE is LOW, the output follows the input; when OE is HIGH, the output enters a high-impedance (3-state) condition, effectively disconnecting it from the bus. This allows multiple drivers to share a single bus without conflict.
What package options are available for the SN74HC125DR, and what does the 'DR' suffix mean?
The SN74HC125DR comes in a 14-pin SOIC (Small Outline IC) package with a 3.9mm body width. The 'DR' suffix denotes the tape-and-reel packaging format with 2500 units per reel, which is ideal for automated SMT assembly. The device is also available in other packages such as PDIP (DIP-14).
Is the SN74HC125DR RoHS compliant?
Yes, the SN74HC125DR is RoHS compliant and lead-free (Pb-free), as indicated by its JESD-609 code e4. Texas Instruments also offers the SN74HC125DRG4 variant, which carries the G4 suffix denoting green/halogen-free compliance for stricter environmental requirements.
