Bookmark or Share- What's the difference between 0 and high impedance (or floating)?A tri-state output can either drive the output line high, drive it low, or enter "hi-Z state" (a.k.a., "high impedance state", a.k.a., "disabled", a.k.a., "tri-stated"). In high-Z state, the output pin effectively is disconnected. The purpose of tri-state outputs is to allow more than one chip to drive the same line, which usually is called a ...
- "Tristate a pin" - Electrical Engineering Stack Exchange42. "Tristate" means a state of high impedance. A pin can either pull to 0 V (sinking current, generally), pull to 5 V (sourcing current, generally), or become high impedance, like an input. The idea is that if a pin is in high impedance state, it can be pulled to high or low by an external device without much current flow.
- digital logic - What is the advantage of a tri-state output ...I'm trying to understand what is the use of tri-state output and what is the advantage of using it. Below depicts both two-state and tri-state output: According to the above logic, it seems to me two-state output can only be ON or OFF. But in tri-state case, the output can be ON, OFF or floating. So to me the only difference is the floating ...
- Tristate buffer - Electrical Engineering Stack ExchangeA typical CMOS tri-state inverter is shown below. You can see that the input capacitance is just gate capacitance plus any parasitics, regardless of the value of OE. MOSFET gates are capacitive. They may draw a very small leakage current but this is in most cases negligible.
- Tri-State Detection - Electrical Engineering Stack ExchangeA simple XOR tri-state detector. With the resistor values shown in Figure 2 this circuit requires a threshold of V+/2. With IN floating / tri-stated the upper and lower XOR inputs are pulled to 2/3 V+ (high) and 1/3 V+ (low) respectively. The output will turn on.
