SN74AUC2G08DCTR

Overview

The SN74AUC2G08DCTR is a dual 2-input positive-AND gate from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V, 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 1.5 ns at 1.8 V with a 30-pF load. It includes Ioff support for partial-power-down mode and offers ESD protection exceeding 2000 V (human-body model). The DCTR variant utilizes an SSOP package.

Feature Summary

• Dual 2-input AND logic function in a compact surface-mount package
• Low power consumption with 10-μA current draw at 1.8 V
• Supports mixed-mode operation with 3.6-V tolerant inputs
• Integrated Ioff circuitry prevents damaging backflow during partial-power-down

Applications

• Portable battery-powered consumer electronics
• Mixed-voltage signal translation between 1.8-V and 3.6-V domains
• Partial-power-down configurations requiring output isolation

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the SN74AUC2G08 series includes multiple variants such as YZP (NanoFree) and DCU (VSSOP). Ensure the selected part matches the required thermal impedance and physical dimensions for the target PCB layout. Confirm RoHS compliance and moisture sensitivity level ratings prior to assembly.

Selection Notes

Select this component when sub-1-V operability and low power consumption are critical design constraints. The AUC series is specifically designed for 1.8-V systems but supports wider voltage ranges up to 2.7 V. Consider the package options based on available board space and thermal requirements, noting that the NanoFree package offers the smallest footprint.

Part Context

This device belongs to the Texas Instruments AUC Little Logic family, which focuses on high-speed, low-power performance in small packages. The AUC series bridges the gap between traditional CMOS and advanced logic families by offering optimized performance at lower supply voltages while maintaining compatibility with standard logic levels.

Replacement Considerations

Direct replacements include other SN74AUC2G08 variants with different packaging, such as SN74AUC2G08DCUR (VSSOP) or SN74AUC2G08YZPR (NanoFree), provided the pinout and electrical characteristics remain compatible with the existing design.
