SN74AUC1G19YZPR

Overview

The SN74AUC1G19YZPR is a single-channel 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 and utilizes a NanoFree DSBGA package with six pins. The device features an active-low enable input (E) and a data input (A). When enabled, it routes the input signal to output Y0 in true form and to output Y1 in complemented form. It supports mixed-mode signal operation with 3.6-V I/O tolerance and includes Ioff circuitry for partial-power-down applications.

Feature Summary

• Provides 1-of-2 decoding functionality by routing a single data input to two distinct outputs based on an enable control signal.
• Incorporates Ioff circuitry to disable outputs during partial-power-down states, preventing damaging current backflow through the device.
• Features high electrostatic discharge protection ratings exceeding standard human-body and machine model thresholds.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'YZPR' corresponds to the DSBGA package type and tape-and-reel quantity before procurement. Confirm that the design environment supports the recommended operating conditions and thermal requirements for the NanoFree package configuration.

Selection Notes

Select this component when a compact 1-of-2 demultiplexer is required for low-voltage digital systems. It is suitable for designs needing sub-1-V operability and mixed-mode signal handling with 3.6-V I/O tolerance. Ensure the application benefits from the small footprint of the NanoFree package.

Part Context

This part belongs to the SN74AUC1G series of Little Logic devices manufactured by Texas Instruments. The AUC family is optimized for low-voltage operation and high-speed performance. The SN74AUC1G19 specifically functions as a decoder/demultiplexer, distinguishing it from inverters or buffers within the same product line.

FAQ

How does the SN74AUC1G19 handle partial-power-down scenarios?

The device includes Ioff circuitry that disables the outputs when powered down, preventing damaging current backflow through the device.

What is the function of the Enable (E) pin?

The Enable (E) pin is active-low. When E is low, the device passes the data from input A to outputs Y0 and Y1. When E is high, the outputs remain in a high state regardless of the input A.
