SN74LS126AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS126AN is a quadruple bus buffer gate manufactured by onsemi, belonging to the LS (Low-power Schottky) logic family. It features four independent non-inverting buffers with three-state outputs and active-high output enable inputs. The device operates within a standard voltage range typical for TTL logic and utilizes a 14-pin DIP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the part number suffix 'AN' corresponds to the specific 14-pin DIP package variant required for your design. Confirm the manufacturer origin, as this part number may be sourced from Texas Instruments or onsemi depending on the supply chain. Ensure the datasheet matches the specific electrical characteristics of the LS series.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring isolated signal buffering with controllable drive states. It is suitable for applications needing to connect multiple sources to a single bus without interference. Consider the power consumption and speed requirements of the LS series compared to other logic families like HC or HCT.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the widely used 74xx logic family, specifically the 74LS126 variant. It serves as a fundamental building block in digital electronics for managing data flow on buses. Similar parts include the 74LS125, which differs by having active-low enable inputs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the SN74LS125N, though it requires active-low enable signals. Other equivalents are the MC74LS126AN from onsemi or variants from Texas Instruments. Verify pin compatibility and logic polarity before substitution.
