SN74AUC1G32DBVR

Overview

The SN74AUC1G32DBVR is a single 2-input positive-OR gate from the Texas Instruments 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 ±8 mA output drive current at 1.8 V. The device includes Ioff partial-power-down mode for back-drive protection and offers ESD protection exceeding 2000 V via the human-body model. It is housed in a compact SOT-23 (DBV) package with five pins.

Feature Summary

• Operates at sub-1-V supply voltages down to 0.8 V
• Includes Ioff circuitry to prevent damaging backflow during partial power-down
• Provides high ESD protection ratings for robust manufacturing handling

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 the specific ordering suffix to confirm the package type and reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the selected variant matches the required operating temperature range and lead finish options available in the official product folder.

Selection Notes

Select this component when designing low-voltage digital circuits requiring a simple OR function. It is suitable for mixed-mode signal environments due to its 3.6-V I/O tolerance despite lower supply operation. Consider the SOT-23 package for space-constrained board layouts where minimal footprint is critical.

Part Context

This device belongs to the SN74AUC1G series of Little Logic devices optimized for ultra-low voltage applications. The AUC family provides performance improvements over previous generations while maintaining compatibility with standard logic interfaces. The DBV suffix specifically denotes the SOT-23 surface-mount package configuration.
