SN74AUC1G02YZPR

Overview

The SN74AUC1G02YZPR is a single 2-input positive-NOR gate from the Texas Instruments AUC logic series, housed in a DSBGA-5 package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports an operating temperature range of -40°C to +85°C. The device features a maximum propagation delay of 2.4 ns at 1.8 V with a 30 pF load. Output drive capabilities include ±9 mA at 2.3 V and ±8 mA at 1.65 V. Static power consumption is limited to a maximum of 10 µA.

Feature Summary

• Supports partial-power-down mode via Ioff circuitry to prevent damaging backflow current when powered down.
• Provides ESD protection exceeding JESD 22 requirements for human-body, machine, and charged-device models.
• Features latch-up performance exceeding 100 mA per JESD 78 Class II specifications.

Applications

• Mixed-mode signal operation supporting 3.6-V I/O tolerance
• Sub-1-V operable low-voltage logic circuits
• Portable consumer electronics requiring minimal footprint

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the YZP designation indicates the NanoFree DSBGA configuration. Confirm that the RoHS compliance status aligns with project environmental regulations. Ensure the moisture sensitivity level rating meets the assembly process constraints. Cross-reference the active production status to confirm long-term availability before finalizing component selection.

Selection Notes

Select this component for designs requiring sub-1-V operation or optimized 1.8-V performance. The DSBGA-5 package offers significant space savings compared to standard SOT packages. Verify input transition rates against the specified limits for the target supply voltage. Ensure unused inputs are tied to VCC or GND to maintain proper device operation and prevent floating states.

Part Context

This device belongs to the SN74AUC1Gxx family of Little Logic devices designed for ultra-low voltage applications. The AUC series utilizes advanced semiconductor processes to achieve high speed with minimal power consumption. The YZPR suffix specifically denotes the DSBGA package variant supplied in a tape and reel format for automated surface-mount assembly.

FAQ

How does the Ioff feature benefit system design?

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

What is the maximum input voltage tolerance?

The input voltage range extends up to 3.6 V, allowing the device to tolerate 3.6-V I/O signals even when operating at lower supply voltages.
