VDD (Pin 1): This is the positive power supply pin. It is connected to the power source, which is typically a +5V supply for the CD4093BM96 IC. NC (Pins 5, 9, 13): These pins are not connected to any internal circuitry, so they do not perform any function in the circuit. GND (Pin 14): This is the ground or zero-voltage reference pin, used to complete the circuit. Inputs (Pins 2, 3, 6, 7, 10, 11): The inputs are the logic signals fed into each NAND gate (A and B inputs for gates 1, 2, and 3). Outputs (Pins 4, 8, 12): These are the logic outputs from each NAND gate. They provide the result of the logical operation performed on the inputs.3. Circuit Principle Explanation:
The CD4093BM96 IC contains four independent NAND gates with Schmitt trigger inputs. The Schmitt trigger inputs are designed to offer better noise immunity and sharper switching behavior compared to standard logic gates. The gates implement the NAND logic function, which outputs a logic HIGH (1) when at least one of the inputs is logic LOW (0), and outputs a logic LOW (0) only when both inputs are HIGH.
The four NAND gates are configured in pairs (two gates per pair), and the output from each gate is available at pins 4, 8, and 12.
