SN74LVC138ARSVR

Overview

The SN74LVC138ARSVR is a 3-line to 8-line decoder and demultiplexer manufactured by Texas Instruments. It belongs to the LVC logic family, supporting an operating voltage range of 1.65 V to 3.6 V. The device features three binary address inputs and eight active-low outputs. It includes three enable inputs: two active-low (G1A, G1B) and one active-high (G2). The component operates within a temperature range of -40°C to +85°C and is housed in a TSSOP-16 package.

Feature Summary

• Provides decoding and demultiplexing functions for digital logic circuits
• Features three independent enable inputs for flexible control
• Supports low-voltage operation from 1.65 V to 3.6 V

Applications

• Address decoding in embedded systems
• Demultiplexing data signals in communication interfaces
• Memory chip select generation in microcontroller designs

Procurement Notes

Verify the specific suffix 'SVR' against the manufacturer's official documentation to confirm the exact tape-and-reel quantity and packaging specifications. Ensure the ordering part number matches the required package type and environmental rating for your application.

Selection Notes

Select this component when a low-voltage 3-to-8 decoder is required with active-low outputs. Consider the LVC series for compatibility with modern low-power logic families. Verify that the TSSOP-16 package fits the PCB layout constraints and thermal requirements.

Part Context

This part is part of the SN74LVC138A family of decoders and demultiplexers. It shares functional similarities with other members of the series but differs in package style and manufacturing revision indicated by the suffix. It serves as a standard solution for address decoding tasks in consumer electronics and industrial applications.

Replacement Considerations

Compatible substitutes include SN74LVC138APWR and SN74LVC138ADRE4. Verify pinout compatibility and electrical characteristics before substitution.
