• Driving high-capacitance loads
• Bus interface applications requiring 3-state control

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor data indicates. Confirm the specific ordering suffix matches the required package type. Check RoHS compliance documentation if required by your design specifications. Ensure the device status is active for production use.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with 3-state capability is needed. The ACT series offers TTL compatibility. Consider the SOIC-14 package for surface mount assembly. Verify voltage requirements align with the 4.5V to 5.5V operating range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AC/ACT125 family of quad buffers. It shares features with other variants like the 74ACT125MTC or 74ACT125PC but differs in package style. The SC suffix specifically denotes the 14-lead Small Outline Integrated Circuit (SOIC) package.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include 74ACT125MTC (TSSOP), 74ACT125PC (PDIP), and 74ACT125SJ (SOP). Ensure the replacement maintains the same logic family and output drive capabilities.
