SN74AUC2G00DCUR

Overview

The SN74AUC2G00DCUR is a dual 2-input positive-NAND gate from the AUC logic series, manufactured by Texas Instruments. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.65-V to 1.95-V applications. The device provides ±8-mA output drive at 1.8 V and features a maximum propagation delay of 1.2 ns at 1.8 V. It utilizes a VSSOP-8 (DCU) package with single-ended inputs and outputs. Key electrical characteristics include a low static current of 10 μA at 1.8 V and Ioff support for partial-power-down mode.

Feature Summary

• Supports mixed-mode signal operation through 3.6-V tolerant inputs while operating at lower supply voltages.
• Includes integrated Ioff circuitry that disables outputs to prevent damaging backflow currents during partial-power-down states.
• Features robust latch-up protection exceeding 100 mA per JESD 78 Class II standards.

Applications

• Partial-power-down applications requiring controlled output disabling
• Mixed-mode signal processing circuits
• Low-voltage digital logic systems

Procurement Notes

Verify the specific ordering suffix DCUR corresponds to the VSSOP-8 package configuration required for your design. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer's documentation. Ensure that input pins are tied to valid logic levels to maintain proper device operation. Review the absolute maximum ratings to prevent damage from overvoltage conditions.

Selection Notes

Select this component when a compact dual NAND gate is needed for sub-1-V or 1.8-V logic families. The VSSOP-8 package offers space efficiency for high-density layouts. Consider the 3.6-V input tolerance if interfacing with higher voltage domains. Evaluate the propagation delay specifications against your system timing requirements.

Part Context
