SN74AUC2G08DCUR

Overview

The SN74AUC2G08DCUR is a dual 2-input positive-AND gate from the Texas Instruments AUC logic series, housed in an 8-pin VSSOP package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports temperatures from -40°C to +85°C. The device features ±8-mA output drive at 1.8 V and a maximum propagation delay of 1.5 ns at 1.8 V. Static current consumption is typically 10 μA at 1.8 V.

Feature Summary

• Supports partial-power-down mode via Ioff circuitry to prevent damaging backflow currents when powered down.
• Provides high ESD protection exceeding JESD 22 standards 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 interfaces
• Low power consumption applications requiring sub-1-V operability
• Portable electronics utilizing NanoFree packaging technology

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DCU designation corresponds to the VSSOP configuration. Confirm that the RoHS compliance status aligns with project requirements. Ensure the operating temperature range meets environmental constraints. Check for any additional marking characters indicating assembly or test site variations. Validate that the moisture sensitivity level rating is suitable for the intended reflow soldering process.

Selection Notes

Select this component for designs requiring low-voltage AND logic with minimal footprint. The VSSOP package offers a compact solution for space-constrained PCB layouts. Consider the 1.5 ns propagation delay for timing-sensitive digital circuits. Evaluate the 10 μA static current for battery-powered systems. Ensure input signals remain within the specified voltage limits to maintain reliable operation.

Part Context
