74LVC1G126DBVRG4

Overview

The SN74LVC1G126DBVRG4 is a single bus buffer gate with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and supports unidirectional data flow controlled by an active-high enable signal. The device utilizes a 5-pin SOT-23 package, specifically SC-70 or SOT-753, designed for surface-mount applications. It functions across an extended temperature range from -40°C to +125°C. Key electrical characteristics include a maximum output current of 32 mA and a typical static current of 10 µA.

Feature Summary

• Provides non-inverting buffering for single-channel digital signals
• Features three-state outputs to facilitate bus line driving and isolation
• Operates with low quiescent current for power efficiency
• Compatible with mixed 1.8-V, 2.5-V, 3.3-V, and 5-V environments

Applications

• Portable equipment requiring low-voltage operation
• Consumer electronics utilizing multiple voltage domains
• Computing and infotainment systems
• Telecommunications infrastructure components

Procurement Notes

Verify the complete ordering part number includes the G4 suffix for lead-free and RoHS compliance status. Confirm the package designation matches the required footprint, as DBV indicates the SC-70/SOT-23-5 variant. Ensure the intended operating environment falls within the specified -40°C to +125°C temperature range. Check for any specific moisture sensitivity level requirements during assembly processes.

Selection Notes

Select this component when a single-channel, non-inverting buffer with high drive capability is required in a minimal footprint. It is suitable for designs needing compatibility with both 1.8-V and 5-V logic levels. Consider the 32-mA output drive strength for moderate capacitive loads. Evaluate the 10-µA static current consumption against strict power budget constraints in battery-operated devices.

Part Context

This device belongs to the SN74LVC1G126 family of single bus buffers. It shares functional similarities with other LVC series components but is distinguished by its specific voltage range and drive characteristics. The DBVRG4 designation identifies the specific tape-and-reel packaging and lead-free composition within the broader Texas Instruments logic portfolio.
