The 74HC138DTR2G is a high-speed 3-to-8 line decoder/demultiplexer IC component manufactured by ON Semiconductor. It belongs to the 74HC series of integrated circuits which are widely used in various digital electronics applications. This IC is designed to convert a binary input into one of eight active-low outputs.
Key Features:
1. High-Speed Operation: The 74HC138DTR2G has fast switching speeds, allowing for efficient decoding and demultiplexing functions in digital circuits.
2. 3-to-8 Decoder/Demultiplexer: This IC component takes a 3-bit binary input and provides eight active-low outputs. By decoding the input, it directs the required output line to a LOW state while keeping the remaining output lines HIGH.
3. Active-Low Outputs: The outputs of the IC are active-low, meaning when an output is selected, that specific output line goes LOW while the rest remain HIGH. This facilitates easy interfacing with other digital circuitry.
4. Multiple Enable Inputs: The IC provides multiple enable inputs to control the output selection. It has three enable inputs, namely G1, G2A, and G2B. These inputs allow the selection of various combinations of output lines.
5. Cascadable: The 74HC138DTR2G is designed to be cascaded, enabling multiple ICs to be connected together to form a larger decoder/demultiplexer with even more output lines
