SN74ABT126RGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT126RGYR is a quad bus buffer gate from the ABT logic series, manufactured by Texas Instruments. It features four non-inverting inputs and outputs housed in a 14-VQFN package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 5.1 ns, high-level output current of -32 mA, and low-level output current of 64 mA. It supports surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RGYR corresponds to the 14-VQFN package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure moisture sensitivity level handling procedures are followed during assembly. Cross-reference the datasheet revision date to guarantee parameter accuracy against design requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 5V logic interface requires buffered output with tri-state functionality. Compare propagation delay specifications against system timing constraints. Evaluate package thermal performance for the target application environment. Consider pin compatibility if replacing legacy 74-series buffers in existing designs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT126 family of quad bus buffers. It shares functional similarities with the SN74ABT125 but differs in enable polarity. The RGYR suffix denotes the specific VQFN-14 packaging configuration used for surface-mount applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ABT125RGYR offers identical electrical characteristics but utilizes active-high enable inputs instead of active-low. Verify logic polarity requirements before substituting to ensure correct circuit operation.
