SN74LVC138ARGYR

Overview

The SN74LVC138ARGYR is a 3-line to 8-line decoder and demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and features low dynamic power consumption. The device utilizes a 16-pin VQFN package with an exposed thermal pad, measuring 4x3.5 mm. It includes two active-low and one active-high enable inputs for flexible control. Designed for high-performance memory decoding and data routing, it offers very short propagation delay times suitable for digital signal processing applications.

Feature Summary

• Provides 3-to-8 line decoding and demultiplexing functionality
• Features low dynamic power consumption for energy efficiency
• Includes dual active-low and single active-high enable inputs
• Designed for high-speed memory decoding and data routing

Applications

• High-performance memory decoding systems
• Data routing in digital signal processing circuits
• Wireless connectivity solutions requiring fast switching

Procurement Notes

Verify the specific suffix 'ARGYR' corresponds to the 16-pin VQFN (4x3.5 mm) package with an exposed thermal pad. Confirm the operating temperature range and supply voltage specifications match the design requirements. Ensure compatibility with the target logic family and check for any specific handling instructions related to the small outline package.

Selection Notes

Select this component when designing systems that require precise address decoding or data distribution with minimal latency. The low voltage operation makes it suitable for portable devices. Consider the package size constraints and thermal management needs due to the exposed pad design. Verify that the input logic levels are compatible with the driving source signals.

Part Context

This part belongs to the SN74LVC138A series of decoders and demultiplexers from Texas Instruments. It is part of the LVC logic family, which is optimized for low-voltage applications. The series is commonly used in consumer electronics and industrial control systems where space-saving packages and low power consumption are critical design factors.

Replacement Considerations

Check for direct pin-compatible substitutes within the same LVC family, such as other variants of the SN74LVC138A with different packaging options like SOIC or TSSOP. Ensure any replacement maintains the same voltage range and enable logic configuration.
