SN74LVC2G240DCUR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC2G240DCUR is a dual buffer and line driver from Texas Instruments' LVC logic series. It features two independent channels with inverted outputs and three-state capability. The device operates within a supply voltage range of 1.65 V to 5.5 V, supporting low-voltage digital systems. It utilizes an 8-pin VSSOP surface-mount package. Key electrical characteristics include high output drive currents of ±32 mA for both high and low states. The component ensures reliable performance across an extended industrial temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides dual-channel buffering with inverted signal polarity for data path management.
• Features three-state outputs to facilitate bus-oriented architectures and isolation.
• Delivers strong ±32 mA output drive capability to support transmission lines and loads.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented architecture signal routing
• Clock distribution and buffering
• Memory and microcontroller interface drivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DCUR' to confirm the VSSOP-8 package type and tape-and-reel delivery format. Ensure compatibility with the target PCB footprint and reflow soldering profile requirements. Confirm that the selected supplier provides traceable documentation consistent with Texas Instruments manufacturing standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual inverting buffers with three-state control are required in compact designs. It serves as a suitable alternative to non-inverting variants like the SN74LVC2G126 if signal inversion is needed. Consider the ±32 mA drive strength for driving capacitive loads or transmission lines compared to lower-current logic families.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC2G240 family of dual buffers. It shares functional similarities with other LVC series devices but is distinguished by its inverting polarity and three-state output configuration. The DCUR suffix specifically denotes the plastic small-outline package variant manufactured by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The Nexperia 74LVC2G240DP,125 offers equivalent functionality in an 8-TSSOP package. Verify pinout compatibility and package dimensional tolerances before substituting to ensure proper fit on existing layouts.
