74LVC1G126DBVRE4

Overview

The SN74LVC1G126DBVRE4 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 an operating temperature range from -40°C to +85°C. The device features unidirectional data flow controlled by a high-level enable signal. It provides high output drive capability with maximum output currents of ±32 mA. The component utilizes a 5-pin SOT-23 package, ensuring compact integration in space-constrained designs while maintaining low static current consumption.

Feature Summary

• Provides non-inverting buffering for single-channel digital signals
• Features three-state outputs allowing electrical isolation when disabled
• Supports wide supply voltage operation from 1.65 V to 5.5 V
• Includes Ioff circuitry to prevent excessive current draw during power-down

Applications

• Portable equipment requiring low power consumption
• Battery-powered systems utilizing multiple voltage domains
• High-density memory card interfaces
• Consumer electronics with limited board space

Procurement Notes

Verify the complete ordering part number includes the RE4 suffix to confirm lead-free status and RoHS compliance. Confirm the package designation matches the required SOT-23 footprint. Ensure the temperature grade aligns with the specific industrial or commercial requirements of the target application environment before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a single-channel buffer with high drive strength and low quiescent current. The LVC logic family offers compatibility with both 1.8 V and 3.3 V systems. Consider the SOT-23 package size for dense PCB layouts. Verify that the input voltage levels match the source logic family to ensure proper switching thresholds across the entire operating voltage range.

Part Context

This device belongs to the SN74LVC1G126 series of single bus buffers. It shares functional similarities with the SN74LVC1G125 but differs in control polarity. The LVC series is designed for low-voltage CMOS applications. It serves as a key component in digital signal routing where signal integrity and power efficiency are critical constraints in modern electronic design.

Replacement Considerations

Direct substitutes include SN74LVC1G125DBVRE4, which offers inverted enable logic. Other compatible options within the same family are SN74LVC1G126DCKR and SN74LVC1G126YZPR. Verify pinout compatibility and electrical specifications before substituting.
