SN74AUC1G04DCKRG4

Overview

The SN74AUC1G04DCKRG4 is a single inverter gate from the Texas Instruments AUC logic family, housed in a 5-pin SC-70 package. It operates within a supply voltage range of 0.8 V to 2.7 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device features a maximum propagation delay of 2.2 ns at 1.8 V and provides an output drive current of ±8 mA at 1.8 V. It includes Ioff circuitry for partial power-down support and offers high ESD protection ratings.

Feature Summary

• Supports partial power-down mode via Ioff circuitry to prevent damaging backflow currents
• Provides robust electrostatic discharge protection exceeding JESD 22 standards
• Optimized for 1.8-V operation while maintaining 3.6-V I/O tolerance

Applications

• Portable audio devices such as MP3 players and recorders
• Solid state drives for client and enterprise storage
• Wireless peripherals including headsets, keyboards, and mice

Procurement Notes

Verify the specific ordering suffix 'R' indicates tape and reel packaging configuration. Confirm the 'G4' suffix aligns with current environmental compliance requirements. Ensure the SC-70 package dimensions match the target PCB footprint. Validate that the operating temperature range meets system thermal constraints.

Selection Notes

Select this component when designing low-voltage digital circuits requiring minimal footprint and sub-nanosecond switching speeds. It is suitable for applications needing mixed-signal interfacing due to its input tolerance. Consider the AUC series for superior performance compared to standard CMOS logic families in portable electronics.

Part Context

This part belongs to the SN74AUC1G04 product line, representing Texas Instruments' AUC Little Logic series designed for sub-1-V operation. The DCKRG4 designation specifies the SC-70 surface-mount package and RoHS-compliant manufacturing process. It serves as a fundamental building block for signal inversion in compact embedded systems.
