74LVC2G125DCURE4

Overview

The SN74LVC2G125DCURE4 is a dual bus buffer gate with three-state outputs from the Texas Instruments 74LVC logic family. It operates within a supply voltage range of 1.65V to 5.5V and features non-inverting logic. The device is housed in an 8-VSSOP package, measuring 3.15mm in length and 1.3mm in height. It supports surface mount installation and includes two independent one-bit elements per chip. The component is designed for high-speed digital applications requiring robust signal buffering.

Feature Summary

• Dual configuration providing two independent non-inverting buffer gates within a single compact package
• Three-state output capability allowing effective bus line management and isolation
• Wide operating voltage range supporting both low-power and standard logic interfaces

Applications

• Bus-oriented architectures requiring signal buffering and direction control
• Clock distribution networks for timing signal integrity
• Data acquisition systems needing isolated input buffering

Procurement Notes

Verify the complete part number including the E4 suffix to ensure compliance with specific environmental standards. Confirm the package type matches the design footprint requirements. Check the datasheet revision date to ensure alignment with current manufacturing specifications. Validate that the intended operating temperature range falls within the specified limits for the application environment.

Selection Notes

Select this component when a dual buffer with three-state control is required in a small form factor. Ensure the system voltage aligns with the 1.65V to 5.5V operational range. Consider the propagation delay characteristics relative to the target clock frequencies. Verify that the thermal performance of the VSSOP package meets the power dissipation needs of the circuit design.

Part Context

This device belongs to the SN74LVC2G series, which focuses on low-voltage CMOS technology. The series offers high density and speed suitable for portable and battery-operated devices. The DCURE4 variant specifically denotes the tape and reel packaging format and lead-free composition, distinguishing it from cut-tape or tray alternatives within the same logical family.

Replacement Considerations

Direct substitutes include the SN74LVC2G125DCUR and SN74LVC2G125DCKR. These variants share identical electrical characteristics but differ in packaging format. Cross-referencing with other manufacturers requires verification of pin compatibility and voltage thresholds.
