SN74AUC1G00DBVR

Overview

The SN74AUC1G00DBVR is a single 2-input positive-NAND gate from the Texas Instruments AUC logic series, housed in a DBV (SOT-23) package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports an input voltage up to 3.6 V. The device features a maximum propagation delay of 2.2 ns at 1.8 V with a 30 pF load. Output drive capabilities include ±9 mA at 2.3 V and ±8 mA at 1.8 V. Static current consumption is limited to a maximum of 10 µA.

Feature Summary

• Supports partial-power-down mode via Ioff circuitry to prevent damaging backflow currents when powered down
• Optimized for 1.8-V operation while providing 3.6-V I/O tolerance for mixed-mode signal environments
• Utilizes NanoFree technology which employs the die as the package for compact footprint integration

Applications

• Mixed-mode signal processing requiring 3.6-V I/O compatibility
• Partial-power-down applications utilizing Ioff functionality
• Low-voltage digital logic circuits operating between 0.8 V and 2.7 V

Procurement Notes

Verify that the ordering suffix 'DBVR' corresponds specifically to the SOT-23 (DBV) package type and reel packaging configuration. Confirm the active production status and ensure the component meets the required -40°C to +85°C operating temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a single NAND gate is required in a small SOT-23 footprint with sub-1-V operability. Ensure the design accommodates the 3.6-V maximum input voltage rating if interfacing with higher voltage logic levels. Verify that the ±9 mA output drive capability meets the load requirements at the target operating voltage.

Part Context

This part belongs to the SN74AUC1Gxx family of single-gate logic devices designed for ultra-low power and high-speed applications. The AUC series is characterized by its ability to operate at voltages below 1 V while maintaining fast switching speeds. The DBVR suffix indicates the specific SOT-23 package variant supplied in tape and reel format for automated assembly.
