SN74AUC1G32YEPR

Overview

The SN74AUC1G32YEPR is a single 2-input positive-OR gate from the Texas Instruments AUC series. It operates within a supply voltage range of 0.8 V to 2.7 V, with specific optimization for 1.65-V to 1.95-V applications. The device features Ioff partial-power-down mode and back drive protection. It provides ESD protection exceeding 2000 V via the human-body model and 1000 V via the charged-device model. Maximum propagation delay is 2.4 ns at 1.8 V with a 30 pF load. Static current consumption is limited to a maximum of 10 µA.

Feature Summary

• Operates at sub-1-V levels while maintaining 3.6-V I/O tolerance for mixed-mode signal environments.
• Includes Ioff circuitry to disable outputs during power-down, preventing damaging backflow currents.
• Delivers high-speed performance with a maximum propagation delay of 2.4 ns at 1.8 V.
• Provides robust electrostatic discharge protection exceeding industry standards.

Applications

• Portable audio devices such as MP3 players and recorders
• Solid state drives for client and enterprise systems
• High-definition television and video analytics servers
• Wireless peripherals including headsets, keyboards, and mice

Procurement Notes

Verify the exact package designation YZP corresponds to the DSBGA configuration before procurement. Confirm that the ordering suffix matches the required tape and reel specifications. Ensure compatibility with the intended operating temperature range of -40°C to 85°C. Check for any recent product change notifications regarding material or assembly updates.

Selection Notes

Select this component when a compact single OR gate is required for low-voltage logic circuits. The NanoFree package offers significant space savings compared to standard small outline packages. Consider the 3.6-V input tolerance if interfacing with higher voltage signals in mixed-signal designs. Evaluate the low static current consumption for battery-powered portable applications.

Part Context

This part belongs to the SN74AUC1G32 family of Little Logic devices. The 'YEPR' suffix indicates the specific DSBGA package type and reel packaging format. The device utilizes Texas Instruments NanoFree technology, which integrates the die directly into the package structure for minimal footprint.

Replacement Considerations

SN74AUC1G32YZPR is a confirmed equivalent part number within the same family offering identical functionality and pinout compatibility.
