SN74HC139APWR

The SN74HC139APWR is a versatile, high-speed dual 2-to-4 line decoder/demultiplexer integrated circuit (IC) component. It is part of the HC family of logic chips. This IC is designed to perform the decoding function, which allows selecting one specific output line out of four possible choices based on a two-bit binary input code. Here are some key features of the SN74HC139APWR: 1. Dual 2-to-4 Line Decoder/Demultiplexer: This IC has two independent decoders in a single package. Each decoder can take a two-bit binary input and generate four output lines based on the input code. 2. High-Speed Operation: The SN74HC139APWR ensures high-speed operation, making it suitable for applications where quick response times are required. It has a propagation delay of only a few nanoseconds, enabling efficient and timely decoding. 3. Active-Low Enable Inputs: The IC incorporates active-low enable inputs (E1 and E2) for each decoder. When these inputs are active (low), the decoder begins decoding the input code. These enable inputs provide flexibility in controlling the decoding process. 4. Active-Low Outputs: The decoded outputs (Y0, Y1, Y2, Y3) are active-low, which means that a logical zero appears on the corresponding output line when selected by the input code
