Hi-Z (or High-Z or high impedance) refers to an output signal state in which the signal is not being driven. The signal is left open, so that another output pin (e.g. elsewhere on a bus) can drive the signal or the signal level can be determined by a passive device (typically, a pull-up resistor).

What is high output impedance?
circuit has low output impedance and high input impedance. ... Low output impedance is desired to suck the maximum current from the circuit. High impedance means the circuit draws or gives little power to the signal. low impedance means the circuit draws or gives more power to the signal.
Is high impedance good or bad?
In general: High impedance sources provide high voltage but low current. Equal impedance between source and headphones is good for portable power requirements, but not necessarily for sound quality.
What is the meaning of high impedance in a circuit?
In electronics, high impedance means that a point in a circuit (a node) allows a relatively small amount of current through, per unit of applied voltage at that point. ... In audio systems, a high-impedance input may be required for use with devices such as crystal microphones or other devices with high internal impedance.
Is it good to have high input impedance?
The answer is the high input impedance is good for the amplifier circuit to have a good amplification of the input signal other wise we get low voltage in, so low amplification. I hope this can help, thank you. To get all the voltage from a source to a target without loss. you need high input impedance.
