SN74AUC1G86DBVRE4

Overview

The SN74AUC1G86DBVRE4 is a single 2-input exclusive-OR gate from the Texas Instruments AUC logic series. It operates within a supply voltage range of 0.8 V to 2.7 V and features low static current consumption of 10 µA. The device provides high drive capability with output currents of ±9 mA. Propagation delays are specified at 2 ns at 2.5 V and 2.6 ns at 1.8 V under a 30 pF load. It is housed in a SOT-23-5 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Single-channel 2-input exclusive-OR logic function
• Low power consumption with 10 µA maximum static current
• High drive strength supporting ±9 mA output currents
• Fast switching performance with propagation delays as low as 2 ns

Applications

• Digital signal processing circuits requiring XOR operations
• Parity checkers and error detection logic
• Arithmetic logic units (ALUs) for addition and subtraction
• Control logic in low-voltage embedded systems

Procurement Notes

Verify the complete part number including the RE4 suffix, which indicates tape and reel packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accommodates the SOT-23-5 thermal characteristics and moisture sensitivity level requirements during assembly processes.

Selection Notes

Select this component when a compact XOR gate is required for sub-3V applications. The AUC series offers superior speed-to-power efficiency compared to older LVC or HC families. Consider the ±9 mA drive capability for direct interfacing with moderate loads without additional buffering. Verify input voltage thresholds align with the system's logic levels across the full operating temperature range.

Part Context

This device belongs to the SN74AUC1Gxx family of ultra-low voltage single-gate logic ICs. These components are designed for portable and battery-operated equipment where space and power are critical constraints. The AUC technology utilizes advanced CMOS processes to achieve high-speed operation at significantly reduced supply voltages compared to standard 5V logic families.

Replacement Considerations

The SN74AUC1G86DCKR is a verified pin-compatible alternative in the SC-70 package. Other members of the SN74AUC1Gxx series may serve as functional substitutes if package dimensions and specific electrical parameters such as propagation delay meet the design requirements.
