SN74AUC1G00DCKR

Overview

The SN74AUC1G00DCKR is a single 2-input positive-NAND gate from the Texas Instruments AUC series, housed in a SC-70 (DCK) package. 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 features a maximum propagation delay of 2.2 ns at 1.8 V with a 30-pF load. Output drive capabilities reach ±9 mA at 2.3 V and ±8 mA at 1.8 V. Quiescent current 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.
• Provides high ESD protection exceeding 2000-V human-body model and 200-V machine model ratings.
• Latch-up performance exceeds 100 mA per JESD 78, Class II standards to support mixed-mode signal operation.

Applications

• Mixed-mode signal processing circuits
• Partial-power-down system designs
• Low-voltage logic interfaces

Procurement Notes

Verify the specific ordering suffix 'DCKR' corresponds to the SC-70 package type and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the operating temperature range of -40°C to +85°C aligns with environmental constraints. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and production status.

Selection Notes

Select this component for applications requiring sub-1-V operability and low power consumption. The AUC series is designed specifically for 1.8-V operation while maintaining compatibility with 3.6-V I/O levels. Consider the SC-70 package dimensions for space-constrained layouts. Evaluate the propagation delay characteristics against system timing requirements under varying load conditions.

Part Context

This device belongs to the Texas Instruments AUC Little Logic family, which focuses on ultra-low power and high-speed performance in small packages. The AUC series utilizes NanoFree technology in certain variants, though the DCK variant uses standard SOT packaging. It serves as a fundamental building block for digital logic functions in portable and battery-operated electronics.

Replacement Considerations

SN74AUC1G00DCKRE4 is an equivalent version available in the same SC-70 package.

FAQ

Does the SN74AUC1G00DCKR support partial-power-down mode?

Yes, the device includes Ioff circuitry that disables outputs to prevent damaging current backflow when the device is powered down.

What is the maximum input voltage tolerance?

The input voltage range extends up to 3.6 V, allowing the device to tolerate 3.6-V signals even when operating at lower supply voltages.
