SN74AUC1G32YZAR

Overview

The SN74AUC1G32YZAR is a single 2-input positive-OR gate from the Texas Instruments AUC logic series, designed for sub-1-V operation within a 0.8-V to 2.7-V supply voltage range. It utilizes NanoFree WCSP (DSBGA) packaging with 0.17-mm small bumps and features Ioff circuitry for partial-power-down support. The device provides ±8-mA output drive at 1.8 V, operates over a -40°C to +85°C temperature range, and exhibits a maximum propagation delay of 2.4 ns at 1.8 V.

Feature Summary

• Supports mixed-mode signal operation through 3.6-V I/O tolerance while operating at optimized 1.8-V levels.
• Enables partial-power-down mode via integrated Ioff circuitry that disables outputs to prevent damaging backflow currents.
• Delivers high-speed performance with a maximum propagation delay of 2.4 ns at 1.8 V.

Applications

• Mixed-mode signal processing in low-voltage systems
• Partial-power-down applications requiring safe current isolation
• High-density digital logic circuits utilizing compact DSBGA packages

Procurement Notes

Verify the specific ordering suffix YZA against the manufacturer's latest documentation to confirm package type and lead-free status. Ensure design compatibility with the specified 0.17-mm bump pitch and thermal impedance requirements. Confirm that the selected component meets all recommended operating conditions for the intended supply voltage and temperature range before finalizing procurement.

Selection Notes

Select this component when a compact single-channel OR gate is required for sub-1-V to 2.7-V applications. It is suitable for designs needing 3.6-V I/O tolerance and partial-power-down capabilities. Consider the NanoFree DSBGA package for space-constrained layouts requiring minimal footprint and low thermal impedance compared to standard plastic packages.
