Product Overview: SN74S139ANSRE4

The SN74S139ANSRE4 is a high-performance integrated circuit designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This device is a dual 2-line to 4-line decoder/demultiplexer that is part of the 74S series, known for its fast switching speeds and Schottky TTL (Transistor-Transistor Logic) technology.

Key Features

• Logic Family: The device belongs to the 74S series, which ensures high-speed operation typically associated with Schottky TTL logic circuits.
• Dual Functionality: It incorporates two individual 2-line to 4-line decoders in a single package, which can be used independently or combined for a wide range of applications.
• Decoding Capability: Each half of the SN74S139ANSRE4 can decode a binary-coded input into one of four mutually exclusive outputs, making it ideal for applications such as data multiplexing, memory address decoding, and function generation.
• Active Low Outputs: The outputs of the device are active low, which means that they are in a low state when selected, providing compatibility with many other TTL logic families.
• Package Type: This particular model is available in an SOP (Small Outline Package), which is suitable for surface mount technology and is preferred for space-constrained applications.
• Supply Voltage Range: The SN74S139ANSRE4 operates over a wide range of supply voltages, typically from 4.75V to 5.25V, which is standard for 74S series devices.
