SN74LVC2G126YZAR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2G126YZAR is a dual bus buffer gate with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and supports partial-power-down mode via Ioff circuitry. The device features inputs that accept voltages up to 5.5 V, ensuring compatibility with 5-V systems. It provides an output drive of ±24 mA at 3.3 V and exhibits a maximum propagation delay of 4 ns at 3.3 V. The component utilizes the NanoFree YZA package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports partial-power-down applications through integrated Ioff circuitry that disables outputs to prevent damaging current backflow when powered down.
• Features inputs capable of accepting voltages up to 5.5 V, allowing direct interfacing between 1.65-V and 5.5-V systems.
• Provides high-drive capability with ±24-mA output drive at 3.3 V for reliable signal transmission.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial-power-down applications requiring controlled output disabling during power transitions
• Bus-oriented connections in low-voltage embedded systems
• Interface circuits bridging different voltage domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'YZAR' corresponds to the NanoFree WCSP (DSBGA) package configuration. Confirm the marketing status as NRND (Not Recommended for New Designs) to ensure alignment with long-term availability requirements. Check RoHS compliance details regarding Green classification and SnAgCu lead finish before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring dual non-inverting buffers with 3-state control in compact packaging. Ensure the application environment stays within the -40°C to 85°C operating temperature range. Verify that the required output drive strength and propagation delay meet system timing constraints under the intended supply voltage conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC2G126 family of dual bus buffer gates. It is distinct from other variants like the SN74LVC2G126DCUR due to its specific NanoFree YZA package type. The device is classified as NRND, indicating it is not recommended for new designs but remains in production for existing customers.
