What is a tristate devices?
A tristate device is a device that has three states instead of two. The normal states are low and high, where the output is pulled down or up by turning on one of the two output transistors. The third state is floating, where neither transistor is turned on. Tristate devices are useful in a bus design where, for instance, more than one device can drive a data bus, but only one at a time.
How tristate devices are used in bus base system?
Tristate devices are used in bus based systems to allow multiple bus drivers to control the bus, each at different times, while all the rest are allowed to read the bus. Only one device can drive the bus at any one time. All the others "tristate" or float, so they neither drive the bus low nor high.
How tristate occurs in a microcontroller?
Tristate in a microcontroller occurs when a pin is configured to operate in a high-impedance state, effectively disconnecting it from the circuit. This is typically achieved by configuring the pin as an input or by setting it to a special mode that allows it to neither drive a high nor a low signal. This state is useful for preventing bus contention when multiple devices share the same communication lines, allowing only one device to drive the line at any given time. In this way, tristate control is essential for managing data flow in multi-device environments.
What is the tristate area of New York?
The "tristate area" of New York consists of New York, New Jersey and Connecticut.
What is tristate bus and how it used in microprocessor?
In Microprocessor based system devices are connected n parallel through the bus in this situation it is required that one device is interact with the bus at a time .If more than one device make communication wid bus then more then one signal is places that they will produce damaging current known as Bus Contention.To avoid bus contention tristate buffer are placed between buses and peripheral...
What are tristate lines of dma 8257?
Tristate lines in the context of the DMA 8257 refer to the control lines that can be in one of three states: high, low, or high impedance (floating). This high impedance state allows multiple devices to share the same bus without interfering with each other, as it effectively disconnects the device from the bus when it is not actively transmitting data. The tristate feature is crucial for managing data transfers between the CPU and peripherals in a system, enabling efficient communication and minimizing conflicts.
