74LVC2G126DCTRG4

Overview

The SN74LVC2G126DCTRG4 is a dual buffer and line driver from the Texas Instruments 74LVC series. It features two non-inverting buffers with three-state outputs, operating within a supply voltage range of 1.65V to 5.5V. The device provides high drive capability with output currents of 32mA for both high and low states. It is housed in an 8-pin Small Outline package (SOIC) with a width of 2.95mm and height of 1.29mm. The component supports surface mount installation and operates across a temperature range of -40°C to +125°C.

Feature Summary

• Dual non-inverting buffer configuration with independent control
• Three-state output capability for bus-oriented applications
• Wide supply voltage operation supporting 1.65V to 5.5V systems
• High drive strength with 32mA output current capability

Applications

• Bus-oriented memory and data transmission systems
• Clock buffering and distribution networks
• High-speed data signal routing in portable devices
• Voltage translation between different logic domains

Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free status and RoHS compliance. Confirm the package type corresponds to the SOIC-8 variant rather than VSSOP or other forms. Ensure the ordering quantity matches the manufacturer's standard packaging requirements. Cross-reference the datasheet revision to confirm pinout and electrical characteristics remain consistent with the design specifications.

Selection Notes

Select this component when a dual-channel buffer with three-state control is required for bidirectional bus architectures. The wide voltage range allows compatibility with both 1.8V and 5V logic families. Consider the propagation delay specifications relative to the system clock speed. Evaluate the thermal performance under maximum load conditions given the 125°C junction temperature rating.

Part Context

This device belongs to the Texas Instruments 74LVC family of low-voltage CMOS logic. The LVC series is designed for high-speed operation while maintaining low power consumption. The 126 designation specifically identifies the triple-buffer function with three-state outputs. This family serves as a standard solution for interface buffering in modern digital electronics requiring reliable signal integrity.

Replacement Considerations

SN74LVC2G126DCUR is a direct equivalent with identical electrical characteristics and pinout. SN74LVC2G126DCTR offers the same functionality in a tape-and-reel format. Verify that any substitute maintains the three-state output feature and compatible supply voltage range.
