74LVC1G126DBVTE4

Overview

The SN74LVC1G126DBVTE4 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 input voltage up to 5.5 V, allowing for level translation. The device features low static current consumption of 10 µA and provides output drive currents of ±32 mA. It includes integrated Ioff circuitry to prevent excessive current draw during partial power-down modes. The component is housed in a 5-pin SOT-23 package and is rated for operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides non-inverting buffering with three-state output control via the OE pin
• Integrates Ioff circuitry to disable outputs and prevent backflow during partial power-down
• Supports wide supply voltage operation from 1.65 V to 5.5 V with 5.5 V tolerant inputs

Applications

• Portable systems requiring low power consumption
• Consumer electronics utilizing battery-powered supplies
• Computing equipment such as servers and mobile devices
• Industrial control systems operating in harsh environments

Procurement Notes

Verify the complete part number including the E4 suffix to confirm lead-free status and RoHS compliance. Ensure the ordering information matches the specific SOT-23-5 package variant required for your PCB layout. Confirm that the manufacturer source aligns with official Texas Instruments documentation to avoid counterfeit components. Check humidity sensitivity levels and storage conditions prior to assembly.

Selection Notes

Select this component when a single-channel buffer with high impedance state capability is required for signal isolation or line driving. The LVC logic family offers compatibility with various voltage domains due to its wide operating range. Consider the SOT-23-5 package size for space-constrained designs. Verify that the load capacitance requirements fall within the specified limits for the desired propagation delay performance.

Part Context

This device belongs to the SN74LVC1G126 series of single bus buffers. It shares functional similarities with other members of the LVC family but is distinguished by its specific package configuration and manufacturing revisions indicated by the suffix. It serves as a fundamental building block for digital signal routing in mixed-voltage systems.

Replacement Considerations

Compatible substitutes include the SN74LVC1G126DCKT and SN74LVC1G126YZPR. These alternatives offer identical logical functions but differ in physical packaging, such as SC-70 or DSBGA formats. Verify pinout compatibility and thermal characteristics before substituting.
