The 74LV138D,118 is an integrated circuit (IC) component that belongs to the 74LV138 family. It is a 3-to-8 line decoder/demultiplexer with active low outputs. Here is an overview of its key features:
1. Binary to Octal Decoder: The IC acts as a decoder, converting a 3-bit binary input into an output that selects one of the eight output lines (Y0 to Y7).
2. Active Low Outputs: The outputs (Y0 to Y7) are active low, which means they provide a low signal when selected, and a high signal when not selected.
3. Enable Input (G): The IC includes an active low enable input (G) that enables or disables the decoder functionality. When G is high, the IC is disabled, and all the output lines remain in high state irrespective of the input.
4. Three Binary Inputs (A, B, C): The IC has three binary inputs (A, B, and C) that serve as the input lines for the decoder. These inputs determine which output line is selected, depending on the binary value applied.
5. Cascadable IC: The IC is designed to be cascaded, allowing multiple units to be connected together to create larger decoders, such as 4-to-16 or 5-to-32 line decoders
