SN74AUC2GU04DCKR

Overview

The SN74AUC2GU04DCKR is a dual inverter from the Texas Instruments AUC logic family, designed for ultra-low voltage applications. It operates within a supply voltage range of 0.8 V to 2.7 V and features an SC-70-6 surface-mount package. The device provides two independent inverting channels with open-drain outputs, supporting low static current consumption of 10 uA. It delivers a low-level output current of 9 mA and exhibits propagation delays of 2.5 ns at 2.5 V and 1.2 ns at 1.8 V under standard test conditions.

Feature Summary

• Ultra-low voltage operation optimized for battery-powered systems
• Open-drain output configuration for flexible level shifting
• High-speed signal inversion with minimal power consumption

Applications

• Battery-operated portable electronics
• Low-voltage digital signal processing interfaces
• Level translation between different voltage domains

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the SC-70-6 package dimensions match your PCB footprint requirements. Ensure the open-drain output type aligns with your circuit design, as pull-up resistors are required for proper high-state logic levels. Check for any recent product change notifications regarding pinout or electrical characteristics.

Selection Notes

Select this component when designing circuits requiring sub-1V operation or strict power budget constraints. The open-drain output allows connection to higher voltage buses than the supply rail, provided appropriate pull-up voltages are used. Compare against the non-guaranteed version (SN74AUC2G04) if guaranteed parameters are not critical, though the GU variant ensures specified performance limits.

Part Context

This part belongs to the SN74AUC2G series of dual logic gates, which are part of Texas Instruments' broader AUC family known for high speed and low power. The AUC series utilizes advanced CMOS technology to achieve performance comparable to older families while operating at significantly lower voltages. The SC-70-6 package is a standard small-outline transistor package suitable for space-constrained designs.

Replacement Considerations

The SN74AUC2G04DCKR is a similar device but lacks the guaranteed electrical parameters of the GU variant. For non-open-drain applications, the SN74AUC2G34DCKR offers push-pull outputs. Verify compatibility with the SN74LVC2GU04DCKR if system voltage requirements exceed 2.7 V.
