SN74LV139ARGYR

Overview

The SN74LV139ARGYR is a dual 2-line to 4-line decoder/demultiplexer from the Texas Instruments 74LV series, housed in a 16-pin VQFN package. It operates on a single power supply ranging from 2V to 5.5V and supports mixed-mode voltage operation across all ports. The device incorporates two enable inputs to simplify cascading and data reception. Designed for high-speed memory decoders and data-transmission systems, it features fully buffered inputs representing only one normalized load to the driving circuit. The component includes Ioff circuitry to support partial-power-down mode operation.

Feature Summary

• Supports mixed-mode voltage operation on all ports
• Incorporates two enable inputs to simplify cascading and/or data reception
• Ioff circuitry supports partial-power-down mode operation

Applications

• High-speed memory decoders
• Data-transmission systems
• Partial-power-down applications

Procurement Notes

Verify that the ordering suffix 'RGY' corresponds to the 16-pin VQFN package configuration. Confirm RoHS compliance status and moisture sensitivity level ratings against the latest Package Option Addendum before procurement. Ensure ESD precautions are observed during handling as specified in the datasheet.

Selection Notes

Select this component when a dual 2-to-4 decoder or demultiplexer is required within the 2V to 5.5V operating range. The VQFN package is suitable for space-constrained surface-mount designs. Verify that the propagation delay characteristics at the specific system voltage meet the timing requirements of the target application.

Part Context

This part belongs to the SN74LV139A family of dual 2-line to 4-line decoders/demultiplexers. The 'RGY' suffix specifically denotes the 16-pin VQFN (4.00 mm × 3.50 mm) package variant. Other available packages for this logic function include SOIC, SSOP, TVSOP, SOP, and TSSOP configurations.
