Product Overview: SN74LV139ANSR

The SN74LV139ANSR is a high-performance, dual 2-line to 4-line decoder/demultiplexer integrated circuit (IC) designed and manufactured by Texas Instruments (TI). This device is part of TI's advanced low-voltage CMOS family, which offers a balanced trade-off between speed and power consumption, making it suitable for a wide range of applications in modern electronic systems.

Key Features

• Logic Type: Decoder/Demultiplexer
• Supply Voltage Range: 2V to 5.5V
• Operating Temperature: -40°C to 85°C
• Output Current: High/Low: ±8 mA
• Package: SOP (Small Outline Package)
• Mounting Type: Surface Mount
• Logic Family: LV
• Fabrication Technology: CMOS

Functionality

The SN74LV139ANSR device features two individual 2-line to 4-line decoders, each with its own address input (A and B) and enable input (G). When the enable input is high, all four outputs of the respective decoder are forced low. Conversely, when the enable input is low, one of the four outputs will go high based on the combination of the address inputs, thus allowing for the demultiplexing function.

Applications

With its versatile decoding capability, the SN74LV139ANSR is ideal for a variety of applications, including:

• Memory address decoding
• Data routing
• Control signal generation
• Function selection in multiplexed applications

Quality and Reliability

The SN74LV139ANSR is designed to meet the stringent quality standards of Texas Instruments. It provides a reliable solution for systems that require low-voltage operation and minimal power consumption without sacrificing speed. The device is RoHS compliant, ensuring it meets global environmental standards and is suitable for use in a wide range of commercial and industrial applications.
