The 74HCT157PW,118 is an Integrated Circuit (IC) component used in digital electronic systems. It belongs to the 74HCT family of ICs, which are high-speed CMOS devices.
Key features of the 74HCT157PW,118 include:
1. Quad 2-input multiplexer: The IC contains four independent 2-input multiplexers. A multiplexer is a digital circuit that selects one of the multiple input signals and forwards it to a single output.
2. Data selection: Each multiplexer in the 74HCT157PW,118 has two data inputs, allowing the selection between two different data inputs.
3. Common select inputs: The IC has two common select inputs (SA and SB), which are used to control the selection of data input lines. By manipulating these select inputs, the desired data input is chosen to be passed on to the output.
4. Enable input: The 74HCT157PW,118 features an active low enable input (E). When the enable input is at a logic low state, the multiplexers are disabled, and the outputs are in a high impedance state.
5. Buffered outputs: The IC provides four separate buffered outputs that correspond to each of the multiplexers.
6. Wide supply voltage range: The 74HCT157PW,118 is designed to operate with a wide supply voltage range, typically from 4.5V to 5
