SN74AUC1G32DBVRE4

Overview

The SN74AUC1G32DBVRE4 is a single 2-input positive-OR gate from the AUC logic family, designed for operation within a supply voltage range of 0.8 V to 2.7 V. It features a maximum propagation delay of 2.4 ns at 1.8 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device includes Ioff partial-power-down mode to prevent backflow current when powered down. It is housed in a 5-pin SOT-23 package and operates across a temperature range of -40°C to 85°C.

Feature Summary

• Operates at sub-1-V supply voltages while maintaining high-speed performance.
• Supports mixed-mode signal environments through 3.6-V I/O tolerance.
• Includes Ioff circuitry to disable outputs and prevent damaging backflow during partial power-down states.

Applications

• Portable audio devices such as MP3 players and recorders
• Solid-state drives for client and enterprise storage
• Wireless peripherals including headsets, keyboards, and mice

Procurement Notes

Verify that the ordering suffix RE4 corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS compliance standards and matches the intended moisture sensitivity level for your manufacturing environment. Ensure compatibility with the designated SOT-23 footprint on the printed circuit board layout.

Selection Notes

Select this component for designs requiring low-voltage operation below 1.8 V where minimal power consumption is critical. The AUC series offers superior speed compared to standard LVC families at equivalent voltages. Consider the 3.6-V input tolerance if interfacing with higher voltage logic domains without additional level shifting components.

Part Context

This part belongs to the SN74AUC1Gxx series of single-gate Little Logic devices from Texas Instruments. These components utilize NanoFree technology concepts to provide compact solutions for space-constrained portable electronics. The AUC family is optimized for battery-powered applications requiring extended operational life and fast switching speeds.

Replacement Considerations

SN74AUC1G32DBVR is the non-green variant of the same logical function and package type. SN74LVC1G32DBVTG4 serves as a functional alternative but operates at higher voltage levels up to 5.5 V and lacks the sub-1-V capability of the AUC series.
