Best Answer

A tri state (bus driver) device is a device that can be active low, active high, or floating. The use of a tri state device is that several of them can be connected to a single bus line and, so long as only one of them is non-floating, the bus line can be driven by multiple senders. The data bus is most often implemented with tri state drivers.

How tri state device can be used to control the direction of a data bus?

tri state devices carry either 0 or 1 which represents the current state o the data bus. If the tri-state device stores 1, then the data bus carries information.If the tri-state device carries 0,then the data bus is empty.


What is a tri state device?

tri state means three states of operation. usually it is used on data buss whereby data is transferred to peripheral devices called I/O the transfer is 0 or 1 on a try state device if not zero or one the buss goes to open state which makes a tri state device.

When tri state logic device is in the 3rd state then?

When a tri-state logic device is in the third or high-impedance state, it means that it is effectively disconnected from the circuit. This state allows multiple devices to share a common bus without interfering with each other. It is commonly used in buses and multiplexers to prevent conflicts and allow for efficient communication.
