SN74AUC1G19YZPRB

Overview

The SN74AUC1G19YZPRB is a single 1-of-2 decoder/demultiplexer from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V, with specific optimization for 1.65 V to 1.95 V applications. The device features an active-low enable input (E) and a data input (A). When enabled, it routes the input signal to the true output (Y0) or the complemented output (Y1). It utilizes the NanoFree™ DSBGA package.

Feature Summary

• Supports partial-power-down mode via Ioff circuitry to prevent damaging backflow currents when powered down.
• Provides high electrostatic discharge protection exceeding JESD 22 standards for human-body, machine, and charged-device models.
• Features latch-up performance that exceeds 100 mA per JESD 78 Class II specifications.

Applications

• AV Receiver
• Portable Audio Dock
• Blu-ray Player and Home Theater Systems
• Embedded PC
• Solid State Drive (SSD)

Procurement Notes

Verify the exact ordering suffix 'B' against the official TI Package Option Addendum to confirm material type, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required RoHS status and peak reflow temperature ratings for your assembly process.

Selection Notes

Select this component for mixed-mode signal operations requiring 3.6-V I/O tolerance while operating at lower core voltages. Consider the NanoFree™ package for applications demanding minimal footprint. Verify that the maximum propagation delay meets system timing requirements under specific load capacitance conditions.

Part Context

This device belongs to the SN74AUC1G series of sub-1-V Little Logic devices. It is functionally related to other decoders and demultiplexers in the AUC family, sharing similar electrical characteristics and packaging options such as SOT-23, SC70, and DSBGA.
