74AC125SJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74AC125SJX is a quad buffer with 3-STATE outputs housed in a 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm wide. It operates within a supply voltage range of 2.0V to 6.0V and an ambient temperature range of -40°C to +85°C. The device features four independent non-inverting buffers. At 5.0V, propagation delays are typically 5.5ns for high-to-low and 5.0ns for low-to-high transitions, with maximums of 7.0ns. Output drive capability reaches ±24mA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the ordering information table. The 'SJ' suffix denotes the 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm wide. Confirm that the 'X' suffix indicates tape and reel packaging availability if required for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with tri-state functionality is needed for bus systems. Ensure the operating voltage falls between 2.0V and 6.0V. Consider the SOP-14 package dimensions for PCB layout constraints. Verify thermal requirements as power dissipation depends on load capacitance and switching frequency.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the AC/ACT logic family, characterized by CMOS technology and high-speed operation. The 74AC125 series serves as a direct upgrade to older 74HC or 74HCT devices in terms of speed, while maintaining compatibility with various logic families through appropriate voltage selection.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalent parts from other manufacturers such as NXP or Texas Instruments offering the same quad buffer tri-state function in a compatible SOP-14 package. Ensure pinout compatibility and electrical specifications match the original design requirements.
