SN74AUC2G86DCUR

Overview

The SN74AUC2G86DCUR is a dual 2-input exclusive-OR gate from Texas Instruments' AUC logic series. It operates within a supply voltage range of 0.8 V to 2.7 V and features single-ended inputs and outputs in an 8-pin VSSOP package. The device provides ±8 mA output drive at 1.8 V and maintains low power consumption with a maximum ICC of 10 µA. It supports surface-mount installation and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides dual independent 2-input exclusive-OR logic functionality
• Operates on ultra-low voltage supplies ranging from 0.8 V to 2.7 V
• Delivers high-speed signal processing capabilities
• Ensures low static power consumption for energy-efficient designs

Applications

• Data acquisition systems requiring logical comparison
• Low-voltage digital control circuits
• Portable battery-powered electronic devices
• Signal integrity verification in communication interfaces

Procurement Notes

Verify the complete part number including the DCUR suffix to confirm the specific VSSOP-8 package and reel packaging configuration. Ensure compatibility with the target PCB footprint and soldering profile. Confirm that the design environment supports the specified 0.8 V to 2.7 V operating voltage range and thermal requirements for the intended application scenario.

Selection Notes

Select this component when designing circuits that require exclusive-OR logic under strict low-voltage constraints below 3.3 V. It is suitable for applications demanding minimal power dissipation and compact board space. Consider the propagation delay characteristics and output drive strength relative to the load capacitance to ensure signal integrity at the desired switching speeds.

Part Context

This device belongs to the SN74AUC2Gxx family of ultra-low-power CMOS logic gates. The AUC series is engineered for modern portable electronics, offering performance comparable to higher voltage families while significantly reducing power usage. The dual-gate configuration allows for efficient implementation of complex logic functions within a minimal footprint.

Replacement Considerations

Check for SN74AUC2G86DCTR as an alternative packaging option within the same functional family. Verify pinout compatibility and electrical specifications before substituting with other XOR gates from different manufacturers or logic families.
