## Controlled Inverter

The **Controlled Inverter** circuit element is a controlled gate that inverts the input signal when enabled. As illustrated in the circuit, this element includes an **Enable** input that controls whether the input is inverted at the output or the output is disconnected from the circuit.

- If the **Enable** input signal is HIGH, the controlled inverter gate inverts the input signal (behaves like a NOT gate).
- If the **Enable** input signal is LOW, the controlled inverter gate passes a high impedance signal which effectively disconnects its output from the circuit.

If required, a user can change the orientation of the circuit element using the arrow keys on the keyboard or editing the value of the **Direction** attribute available in the **PROPERTIES** panel for the **Controlled Inverter** circuit element.

> Properties that can be customized in the **PROPERTIES** panel include: **Direction, BitWidth**

## TriState Buffer

The **TriState** buffer circuit element behaves similar to a buffer. As Figure 4.17 illustrates, this circuit element includes an additional **Enable** input that controls whether the primary input is passed to its output or not.
