How to Use inverter: Examples, Pinouts, and Specs

The Surya SWE Inverter is an electronic component designed to invert the logic state of an input signal. When a high voltage level (logic 1) is applied to its input, it outputs a low voltage level (logic 0), and vice versa. This component is essential in digital circuits for implementing logical NOT operations and is commonly used in applications such as signal conditioning, logic gates, and digital signal processing.

• Supply Voltage (Vcc): 3.3V to 5V
• Input Voltage (Vin): 0V to Vcc
• Output Voltage (Vout): 0V to Vcc
• High-level Input Voltage (VIH): 2V min (at Vcc = 5V)
• Low-level Input Voltage (VIL): 0.8V max (at Vcc = 5V)
• High-level Output Current (IOH): -4 mA max (source current)
• Low-level Output Current (IOL): 8 mA max (sink current)
• Propagation Delay (tpd): 10 ns typical (at Vcc = 5V)
• Operating Temperature Range: -40°C to 85°C

1. Connect the Vcc pin to the positive supply voltage (3.3V to 5V).
2. Connect the GND pin to the ground of the power supply.
3. Apply the input signal to the IN pin.
4. The inverted output can be taken from the OUT pin.

• Ensure that the supply voltage does not exceed the maximum rating to prevent damage.
• The input signal voltage should be within the range of 0V to Vcc.
• Avoid loading the output with a current higher than the specified output current ratings.
• Use bypass capacitors close to the Vcc pin to filter out noise and provide a stable supply.
• Keep the propagation delay in mind when designing high-speed digital circuits.

• No Output Signal: Ensure that the Vcc and GND pins are properly connected and that the supply voltage is within the specified range.
• Weak Output Signal: Check if the output is not overloaded beyond its current sinking/sourcing capability.
• Unexpected Output Behavior: Verify that the input signal voltage levels are within the VIH and VIL specifications.

• Double-check the connections and solder joints for any shorts or opens.
• Measure the supply voltage and input signal levels with a multimeter or oscilloscope.
• If the component is not functioning as expected, replace it to rule out the possibility of a defective inverter.

Q: Can the Surya SWE Inverter be used with an Arduino UNO? A: Yes, the inverter can be used with an Arduino UNO, provided that the operating voltage levels are compatible.

Q: What is the maximum frequency the inverter can handle? A: The maximum frequency is determined by the propagation delay. For a 10 ns delay, the theoretical maximum frequency is around 100 MHz. However, practical limits due to circuit layout and other factors will be lower.

Q: Is it necessary to use a current-limiting resistor with the output? A: No, a current-limiting resistor is not required for the output unless you are driving a load that exceeds the specified output current ratings.

// Define the inverter input and output pins
const int inverterInputPin = 2;
const int inverterOutputPin = 3;

void setup() {
  // Set the inverter input pin as OUTPUT
  pinMode(inverterInputPin, OUTPUT);
  // Set the inverter output pin as INPUT
  pinMode(inverterOutputPin, INPUT);
}

void loop() {
  // Send a HIGH signal to the inverter input
  digitalWrite(inverterInputPin, HIGH);
  // Read the inverted output from the inverter
  int invertedSignal = digitalRead(inverterOutputPin);
  // Output the inverted signal to the Serial Monitor
  Serial.println(invertedSignal);
  // Wait for a second
  delay(1000);
  
  // Send a LOW signal to the inverter input
  digitalWrite(inverterInputPin, LOW);
  // Read the inverted output from the inverter
  invertedSignal = digitalRead(inverterOutputPin);
  // Output the inverted signal to the Serial Monitor
  Serial.println(invertedSignal);
  // Wait for a second
  delay(1000);
}

Note: The above code assumes that the inverter is connected to the Arduino UNO with the input pin connected to digital pin 2 and the output pin connected to digital pin 3. Adjust the pin assignments as necessary for your specific circuit configuration.
