SN74AUC1G19DRLR

Overview

The SN74AUC1G19DRLR is a single-channel 1-of-2 decoder/demultiplexer from the Texas Instruments AUC series. It operates within a supply voltage range of 0.8 V to 2.7 V and features an active-low enable input (E) and a data input (A). The device provides two outputs: Y0 (true) and Y1 (complement). When enabled, it buffers the data on input A to the respective outputs. It supports mixed-mode signal operation with 3.6-V I/O tolerance while optimized for 1.8-V operation.

Feature Summary

• Supports sub-1-V operation down to 0.8 V for low-power applications
• Features Ioff circuitry to prevent damaging current backflow during partial-power-down mode
• Provides high electrostatic discharge protection exceeding JESD 22 requirements
• Optimized for mixed-mode signal environments with 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
• Embedded PC systems and personal digital assistants

Procurement Notes

Verify the specific package variant against the orderable addendum in the datasheet, as the DRL suffix denotes the SOT-5X3 package. Confirm that the required operating temperature range aligns with the -40°C to 85°C specification. Ensure design compatibility with the 3.6-V I/O tolerance if interfacing with higher voltage logic levels. Check for any recent product change notifications regarding manufacturing sites or material finishes.

Selection Notes

Select this component when a compact 1-of-2 decoding function is required in space-constrained designs utilizing the NanoFree packaging technology. It is suitable for battery-powered portable electronics due to its sub-1-V operational capability and low static power consumption. Consider the 3.6-V I/O tolerance if the system involves mixed-voltage domains without additional level shifting components.

Part Context

This device belongs to the SN74AUC1Gxx series of Little Logic devices, characterized by ultra-small footprints and low voltage operation. The DRL suffix specifically identifies the SOT-5X3 package option, which offers a minimal footprint compared to standard SOT-23 packages. This series is designed to replace larger legacy logic families in modern portable and embedded applications requiring reduced power and size.
