SN74AUC1G02DBVR

Overview

The SN74AUC1G02DBVR is a single 2-input positive-NOR gate from the Texas Instruments AUC logic series, housed in a SOT-23 (DBV) package. 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 features low power consumption with a maximum static current of 10 µA and supports ±8 mA output drive at 1.8 V. Propagation delay is specified as 2.4 ns maximum at 1.8 V with a 30 pF load. It includes Ioff support for partial-power-down mode and robust ESD protection exceeding JESD 22 standards.

Feature Summary

• Performs Boolean NOR function Y = A + B or Y = A · B in positive logic
• Supports partial-power-down operation via Ioff circuitry to prevent backflow
• Optimized for sub-1-V operation and mixed-mode signal environments
• High latch-up performance exceeding 100 mA per JESD 78 Class II

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DBV designation corresponds to the SOT-23 form factor. Confirm RoHS compliance status and lead finish details against the latest Package Option Addendum. Ensure the operating temperature range aligns with the -40°C to 85°C specification for industrial reliability. Cross-reference the part marking code U02R for production verification.

Selection Notes

Select this component when a compact single-channel NOR gate is required for ultra-low voltage logic levels between 0.8 V and 2.7 V. The AUC series offers superior speed and power efficiency compared to standard CMOS families. Consider the SOT-23 package for space-constrained surface-mount layouts. Verify input transition rates do not exceed specifications to maintain timing integrity.

Part Context

This device belongs to the SN74AUC1Gxx family of Little Logic devices designed by Texas Instruments. The AUC series utilizes advanced semiconductor processes to achieve high performance at very low supply voltages. The NanoFree technology allows for minimal footprint solutions, making it suitable for portable and battery-operated electronic systems requiring efficient power management.

Replacement Considerations

Check for direct pin-compatible alternatives within the same AUC family if different logic functions are needed. Verify that any substitute maintains the 0.8 V to 2.7 V operating range and SOT-23 packaging constraints. Ensure electrical characteristics such as propagation delay and output drive current meet the original design requirements.
