SN74LVC126APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC126APW is a quadruple bus buffer gate with three-state outputs manufactured by Texas Instruments. It belongs to the 74LVC logic series and utilizes CMOS technology. The device operates within a supply voltage range of 1.65 V to 3.6 V. It features four non-inverting channels, each providing one bit of buffering capability. The output type is specified as three-state, allowing for high-impedance isolation when disabled. The component is housed in a 14-TSSOP package with a width of 0.173 inches (4.40 mm). It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel configuration. Ensure compatibility with the target PCB footprint for the 14-TSSOP variant. Confirm RoHS compliance status if required by assembly specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when quadruple buffering with three-state control is required for low-voltage digital circuits. The 1.65 V to 3.6 V supply range makes it suitable for modern low-power systems. Consider the 14-TSSOP package for space-constrained designs requiring surface mount technology. Verify that the operating temperature range meets the environmental requirements of the final application.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader 74LVC family of logic integrated circuits produced by Texas Instruments. The LVC series is characterized by its ability to operate at lower supply voltages while maintaining performance comparable to older standards. The SN74LVC126A specifically addresses the need for buffered bus interfaces in portable and battery-operated devices where power efficiency is critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include SN74LVC126ADBR and SN74LVC126ARGYR, which offer identical logical functionality but differ in package style such as SSOP or VQFN. Direct pin-to-pin replacements may require verification of thermal characteristics and physical dimensions to ensure mechanical fit within the existing design constraints.
