SN74LVC125ANS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC125ANS is a quadruple bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates from 1.65V to 3.6V and features inputs accepting voltages up to 5.5V. The device provides independent line drivers for each of the four channels, controlled by separate output-enable (OE) inputs. It supports propagation delays as low as 4.8ns at 3.3V and includes latch-up performance exceeding 250mA per JESD 17. The component is housed in a 14-pin SOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'NS' corresponds to the SOP-14 package configuration required for your design. Confirm that the selected variant meets the necessary thermal resistance and moisture sensitivity level ratings for your assembly process. Ensure compatibility with the intended operating temperature range and power supply specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple bus buffer with 3-state outputs is required for 1.65V to 3.6V logic applications. It is suitable for designs needing inputs tolerant to 5.5V signals. Consider the SOP-14 package constraints regarding board space and thermal dissipation. Verify that the independent OE control aligns with the system's bus management requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC125A family of quadruple bus buffer gates. The 'NS' suffix specifically denotes the SOP-14 package option within the broader product line. Other variants in this family include different package types such as SOIC, SSOP, TSSOP, WQFN, and VQFN, all sharing the same core logical functionality but differing in physical dimensions and mounting styles.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other SN74LVC125A variants with different packages, such as SN74LVC125AD (SOIC), SN74LVC125APW (TSSOP), or SN74LVC125ARGYR (VQFN). These parts share identical electrical characteristics and pinouts but differ in physical form factor.
