SN74HC126NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC126NS is a quadruple bus buffer gate featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +85°C. The device utilizes a 14-pin Small Outline (SO) package for surface-mount installation. It provides non-inverting buffering with high noise immunity typical of HC logic families.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels for signal conditioning
• Features three-state outputs allowing direct connection to bus structures
• Operates across a broad supply voltage range suitable for various logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• Transceiver buffers for bidirectional data flow

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature rating. Ensure the ordering part number matches the required pin configuration and RoHS compliance status. Cross-reference manufacturer documentation for any recent design or assembly changes affecting this component.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple buffer with three-state capability is required for bus applications. Consider the 2V to 6V supply range compatibility with system power rails. Verify that the 14-pin SO package fits the available PCB footprint and thermal requirements compared to TSSOP or SSOP alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74HC126 family of quadruple bus buffers. It shares functional similarities with other variants like SN74HC126DBR and SN74HC126PWR, differing primarily in package style such as SSOP or TSSOP. The series is designed for general-purpose digital buffering in consumer and industrial electronics.
