The 74FCT157PCTQ is a quad 2-input multiplexer with 16 pins. Its main function is to select between two 4-bit data sources and output the selected data. It has four independent 2-to-1 multiplexers controlled by a common select input (S). Each multiplexer has two data inputs (A and B) and one output (Y). There is also an active-low enable input (E̅) that controls whether the selected data is passed to the outputs.
Here's a brief pin description:
- Pins 1, 4, 10, 13: Output (Y1, Y2, Y3, Y4)
- Pins 2, 5, 11, 14: Input A (A1, A2, A3, A4)
- Pins 3, 6, 12, 15: Input B (B1, B2, B3, B4)
- Pin 7: Ground (GND)
- Pin 8: Enable (E̅)
- Pin 9: Select Input (S)
- Pin 16: VCC (Power Supply)
In operation, when the enable pin is low, the selected data input (A or B) based on the select pin is output on the corresponding Y pin.
