CLVC139AQPWRG4Q1

Overview

The CLVC139AQPWRG4Q1 is an automotive-grade dual 2-to-4-line decoder/demultiplexer manufactured by Texas Instruments. It belongs to the SN74LVC139AQ logic family and features AEC-Q100 qualification for robust performance in vehicle electronics. The device operates with a supply voltage range of 2V to 3.6V and utilizes a 16-pin TSSOP surface-mount package. Designed for low-power applications, it supports efficient data routing and address decoding within constrained power environments typical of modern automotive systems.

Feature Summary

• Dual independent 2-to-4-line decoding and demultiplexing functionality
• Qualified for automotive electronic applications under AEC-Q100 standards
• Operates on low-voltage CMOS technology for energy efficiency

Applications

• Automotive body control modules
• Vehicle lighting control systems
• Infotainment system address decoding

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm that the 'Q1' designation aligns with current AEC-Q100 reliability requirements for your target automotive application tier. Ensure the TSSOP-16 footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring dual independent decoders within a single package to save board space. It is suitable for systems operating between 2V and 3.6V where low static power consumption is critical. Consider its automotive qualification if the design must withstand rigorous environmental stress testing defined for vehicle electronics.

Part Context

This part is part of the SN74LVC139AQ series, which provides high-speed, low-power decoding solutions. The LVC family is known for compatibility with various logic families while maintaining low voltage operation. The automotive variant ensures long-term availability and reliability required for production vehicles.

Replacement Considerations

Check for SN74LVC139APWR or similar non-automotive variants if AEC-Q100 qualification is not strictly required. Verify pinout compatibility with existing designs before substituting with other 2-to-4 decoders from different manufacturers.
