SN74AUC1G08YZAR

Overview

The SN74AUC1G08YZAR is a single 2-input positive-AND gate from the Texas Instruments AUC logic series. It operates within a supply voltage range of 0.8 V to 2.7 V and is optimized for 1.65-V to 1.95-V operation. The device features a maximum propagation delay of 2.4 ns at 1.8 V with a 30-pF load. Output drive capability reaches ±8 mA at 1.8 V, while maximum input and output clamp currents are rated at ±50 mA. Static power consumption is limited to a maximum of 10 µA across the operating temperature range.

Feature Summary

• Supports partial-power-down mode via Ioff circuitry that disables outputs to prevent damaging backflow current when powered down.
• Designed for mixed-mode signal operation with 3.6-V I/O tolerance despite being optimized for lower voltage operation.
• Utilizes NanoFree package technology where the die functions as the package structure.

Applications

• Partial-power-down applications requiring controlled output disabling
• Mixed-mode signal processing circuits
• Low-voltage digital logic systems

Procurement Notes

Verify the specific ordering suffix YZAR corresponds to the NanoFree WCSP (DSBGA) package configuration. Confirm the top-side marking format includes three preceding characters for year, month, and sequence codes, followed by one character for the assembly site. Ensure compatibility with tape and reel packaging requirements for automated assembly processes.

Selection Notes

Select this component for designs requiring a compact single-gate AND function in low-voltage environments. The device is specifically engineered for 1.65-V to 1.95-V operation but remains functional across the broader 0.8-V to 2.7-V range. Consider the NanoFree package dimensions for space-constrained PCB layouts requiring minimal profile.

Part Context

This part belongs to the SN74AUC1Gxx family of single-gate logic devices manufactured by Texas Instruments. The AUC series is characterized by high speed and low power consumption, targeting portable and battery-operated applications. The SN74AUC1G08 specifically implements the Boolean function Y = A • B using positive logic conventions.
