SN74AUC1G04DCKRE4

Overview

The SN74AUC1G04DCKRE4 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 includes Ioff circuitry for partial power-down protection. It provides an output drive current of ±8 mA at 1.8 V and maintains a maximum quiescent current of 10 µA.

Feature Summary

• Supports mixed-mode signal operation through 3.6-V I/O tolerance while operating at lower supply voltages.
• Includes dedicated Ioff circuitry that disables outputs to prevent damaging backflow currents during partial power-down states.
• Provides robust electrostatic discharge protection exceeding JESD standards for human-body, machine, and charged-device models.

Applications

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

Procurement Notes

Verify the E4 suffix indicates lead-free composition compliant with RoHS directives. Confirm the DCK designation corresponds to the SC-70 package variant. Ensure the orderable part number matches the specific tape and reel quantity requirements for your assembly line. Cross-reference the manufacturer's latest packaging addendum for moisture sensitivity level ratings before procurement.

Selection Notes

Select this component when designing circuits requiring sub-1-V operation or low-power consumption. The wide supply voltage range allows flexibility in system architecture. The small SC-70 footprint is suitable for space-constrained portable applications. Verify that the 3.6-V input tolerance meets the interface requirements of higher-voltage control signals.

Part Context

This device belongs to the SN74AUC1G04 series of single inverter gates. The DCKRE4 suffix specifies the SC-70 package type, reel packaging format, and lead-free material composition. It is part of Texas Instruments' NanoFree technology lineup designed for high-density surface-mount applications.
