SN74AUC2G04DBVR

Overview

The SN74AUC2G04DBVR is a dual inverter gate from the Texas Instruments AUC logic family, designed for sub-1-V operation within a 0.8-V to 2.7-V supply voltage range. It operates optimally at 1.65 V to 1.95 V and supports mixed-mode signal environments with 3.6-V I/O tolerance. The device features a maximum propagation delay of 1.7 ns at 1.8 V and provides ±8-mA output drive capability. It incorporates Ioff circuitry for partial-power-down mode support and includes ESD protection exceeding 2000 V via the human-body model.

Feature Summary

• Supports partial-power-down applications through integrated Ioff circuitry that disables outputs to prevent damaging current backflow when powered down.
• Optimized for 1.8-V operation while maintaining 3.6-V I/O tolerance to facilitate mixed-mode signal processing.
• Operates at sub-1-V supply voltages with low power consumption of 10 µA at 1.8 V.

Applications

• Partial-power-down mode operations requiring output isolation
• Mixed-mode signal interfaces between different voltage domains
• Low-voltage digital logic inversion circuits

Procurement Notes

Verify the specific ordering suffix DBVR corresponds to the SOT-23 package and tape-and-reel quantity of 3000 units. Confirm the operating temperature range is -40°C to 85°C. Ensure compatibility with the required supply voltage range of 0.8 V to 2.7 V. Check for RoHS compliance status as indicated in the packaging information.

Selection Notes

Select this component for designs requiring high-speed inversion at very low supply voltages. The AUC series offers superior speed compared to standard LVC families at equivalent voltages. Consider the SOT-23 package constraints for PCB layout. Verify input transition rates do not exceed specified limits to ensure proper switching characteristics.

Part Context

This device belongs to the SN74AUC2Gxx series of ultra-low-voltage CMOS logic gates. It utilizes Texas Instruments' NanoStar or NanoFree package technologies in other variants, though the DBVR uses a standard SOT-23 form factor. It serves as a fundamental building block for complex digital systems requiring minimal power consumption and fast switching speeds.
