SN74AUC1G19DCKT

Overview

The SN74AUC1G19DCKT is a single 1-of-2 decoder/demultiplexer from Texas Instruments, operating within a supply voltage range of 0.8 V to 2.7 V. It features an active-low enable input (E) and a data input (A). When enabled, the device routes the input signal to two outputs: Y0 provides the true logic state, while Y1 provides the complemented state. The component supports partial-power-down mode via Ioff circuitry and includes ESD protection rated at 2000 V for the human-body model. It is housed in a 6-pin SC-70 package.

Feature Summary

• Supports mixed-mode signal operation with 3.6-V I/O tolerance
• Enables partial-power-down applications through Ioff output disabling
• Provides high electrostatic discharge protection across multiple testing standards

Applications

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

Procurement Notes

Verify the specific ordering suffix 'T' confirms the small tape-and-reel carrier quantity of 250 units per reel. Confirm the SC-70 package designation matches the required footprint dimensions. Ensure the revision level aligns with current production data sheets. Validate that the RoHS compliance status meets environmental requirements for the target assembly process.

Selection Notes

Select this component when a low-voltage decoder or demultiplexer is required for portable electronics. The AUC series is optimized for 1.8-V operation but remains functional down to sub-1-V levels. Consider the Ioff feature if the design requires preventing backflow currents during power-down states. Verify that the 3.6-V I/O tolerance satisfies interface requirements with higher voltage logic domains.

Part Context

This device belongs to the SN74AUC1Gxx family of sub-1-V Little Logic devices by Texas Instruments. These components utilize NanoFree technology, which integrates the die directly into the package structure to minimize physical footprint. The family is designed for space-constrained applications requiring low power consumption and high-speed performance in minimal packaging formats.
