SN74AUC1G02YZAR

Overview

The SN74AUC1G02YZAR is a single 2-input positive-NOR gate from the Texas Instruments AUC logic series, 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 up to ±9 mA output drive current. The device incorporates Ioff circuitry to facilitate partial-power-down mode by disabling outputs and preventing backflow. It operates across an extended temperature range of -40°C to +85°C and utilizes a DSBGA-5 (NanoFree) package.

Feature Summary

• Supports sub-1-V operation with optimized performance at 1.8 V
• Includes Ioff circuitry to prevent damaging current backflow during partial-power-down states
• Provides 3.6-V I/O tolerance to enable mixed-mode signal interfacing

Applications

• Mixed-mode signal level translation between low-voltage and 3.6-V systems
• Partial-power-down applications requiring controlled output isolation
• Low-voltage portable electronics operating below 1 V

Procurement Notes

Verify that the ordering suffix matches the specific package type required, as the YZA suffix denotes the NanoFree WCSP variant. Confirm RoHS compliance status and ensure the component meets the specified thermal impedance requirements for the intended PCB layout. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications.

Selection Notes

Select this component when a NOR function is required in ultra-low voltage environments. Ensure the design accommodates the 3.6-V input tolerance if interfacing with higher voltage logic. Verify that the load capacitance remains within the tested limits to maintain the specified propagation delay characteristics.

Part Context

This device belongs to the Texas Instruments AUC Little Logic family, which focuses on high-speed, low-power performance in minimal footprints. The AUC series is engineered for modern portable devices where power efficiency and small package size are critical constraints.

FAQ

How does the Ioff feature benefit system design?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device into the supply lines.

What is the maximum input voltage tolerance?

The inputs are tolerant up to 3.6 V, allowing the device to interface with 3.6-V logic systems while operating at lower supply voltages.
