SN74LS126ANS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS126ANS is a quadruple bus buffer manufactured by Texas Instruments, belonging to the 74LS logic series. It features four non-inverting buffers with three-state outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to 70°C. Key electrical characteristics include a maximum low-level output current of 24mA and a high-level output current of 2.6mA. The component utilizes TTL input specifications and provides unidirectional data flow control.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANS' against the manufacturer's official datasheet to confirm the package type and temperature grade. Ensure compatibility with existing 74LS family requirements. Check for RoHS compliance status if required by project specifications. Confirm pinout alignment with design schematics before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between different logic families or driving multiple loads on a common bus. It is suitable for applications requiring moderate speed and standard drive strength. Consider alternative series like 74HC or 74LVC if lower power consumption or wider voltage ranges are necessary. Verify that the 70°C industrial temperature limit meets environmental constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the widely used 74LS (Low-power Schottky) logic family, known for balanced speed and power dissipation. The 74LS126 specifically addresses bus isolation needs. Similar variants exist with different suffixes indicating package variations or extended temperature ranges. The SN74LS126ADR is a common surface-mount equivalent in the SOIC-14 package.
