74LVC2G126GT,115

Overview

The Nexperia 74LVC2G126GT,115 is a dual bus buffer and line driver featuring three-state outputs controlled by active-high output enable inputs (nOE). It operates within a supply voltage range of 1.65 V to 5.5 V and utilizes an XSON8 package (SOT833-1) with dimensions of 1 × 1.95 × 0.5 mm. The device supports partial power-down applications via IOFF circuitry, which disables outputs to prevent backflow current when powered down. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with 3.3 V or 5 V devices in mixed-voltage environments.

Feature Summary

• Features Schmitt-trigger action at all inputs for tolerance of slower input rise and fall times.
• Includes IOFF circuitry that provides partial power-down mode operation by disabling outputs.
• Provides overvoltage tolerant inputs capable of handling signals up to 5.5 V.

Applications

• Mixed 3.3 V and 5 V voltage translation environments
• Partial power-down system designs requiring backflow prevention
• Bus buffering and line driving applications

Procurement Notes

Verify the specific ordering suffix '115' corresponds to the XSON8 (SOT833-1) package variant. Confirm the required temperature range matches the -40 °C to +125 °C specification defined for this part number. Ensure design compatibility with the 1.65 V to 5.5 V supply voltage limits and check for any recent product change notices affecting the manufacturing location or materials.

Selection Notes

Select this component when a dual buffer with three-state control is required in a leadless XSON8 footprint. It is suitable for applications needing high noise immunity and direct interface with TTL levels. Consider the IOFF feature if the design involves systems where downstream components may remain powered while this device is unpowered.

Part Context

This device belongs to the 74LVC logic family, designed for low-voltage CMOS applications. The 74LVC2G126 series includes multiple package options such as TSSOP8, VSSOP8, and various XSON8 variants. The GT suffix specifically identifies the extremely thin small outline package without leads, distinguishing it from other physical form factors within the same logical function family.
