SN74AUC1G32YZPR

Overview

The SN74AUC1G32YZPR is a single 2-input positive-OR gate from the Texas Instruments AUC logic family. 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 a maximum propagation delay of 2.4 ns at 1.8 V and supports ±8 mA output drive current at that voltage. It includes Ioff partial-power-down mode for back-drive protection and offers ESD protection exceeding 2000 V via the human-body model. The component is housed in a 5-pin DSBGA package.

Feature Summary

• Operates at sub-1-V supply voltages down to 0.8 V
• Includes Ioff circuitry to prevent damaging back-flow currents during partial power-down
• Provides high electrostatic discharge protection exceeding 2000 V human-body model rating

Applications

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

Procurement Notes

Verify the complete part number SN74AUC1G32YZPR against official Texas Instruments documentation to confirm the YZP DSBGA package configuration. Ensure compatibility with the specified 0.8 V to 2.7 V operating range and check for any recent product change notifications regarding manufacturing sites or material compositions before finalizing procurement.

Selection Notes

Select this component for designs requiring low-voltage operation below 1 V or mixed-mode signal environments where 3.6-V I/O tolerance is necessary. The NanoFree™ packaging provides a compact footprint suitable for space-constrained portable electronics. Consider the propagation delay characteristics when designing for high-speed signal processing requirements within the AUC series performance envelope.

Part Context

This device belongs to the SN74AUC1G32 series of single 2-input positive-OR gates manufactured by Texas Instruments. The series utilizes AUC Little Logic technology designed for sub-1-V operation. The YZP suffix specifically denotes the 5-pin DSBGA (NanoFree™) package variant, which integrates the die directly into the package structure for minimal board area consumption.

FAQ

What is the function of the Ioff feature in this device?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device in partial-power-down applications.

Is this device tolerant of 3.6-V signals?

Yes, the SN74AUC1G32YZPR is 3.6-V I/O tolerant, supporting mixed-mode signal operation even when powered by lower voltages.
