The 74LS153PC is a popular Integrated Circuit (IC) component, specifically a dual 4-input multiplexer. It is designed to multiplex two separate data input sources onto a single output line, based on the select inputs. Here is an overview of the key features of this IC component:
1. Dual 4-input Multiplexer: The 74LS153PC consists of two independent 4-input multiplexers in a single IC package.
2. Select Inputs: The IC has two select inputs named S1 and S0, which are used to control the data flow through the multiplexers. These inputs determine which data input source is connected to the output.
3. Data Inputs: Each multiplexer within the IC has four data inputs (A, B, C, D). The two multiplexers can select data from either of the four inputs based on the select inputs.
4. Common Output: The output of the multiplexers is combined into a single output line (Y) which carries the selected data from either MUX1 or MUX2 to the external circuitry.
5. Enable Inputs: The 74LS153PC also includes two active LOW enable inputs (G1 and G2), which allow the multiplexers to be disabled when pulled HIGH. Disabling the multiplexer puts the output into a high-impedance state (floating condition)
