What is 74LS245?
74LS245 Bus Transceiver The TTL 74LS245 is an octal bus transceiver (Transmitter/Receiver) designed for asynchronous two-way communication between two data buses or input/output device.
What is octal bus transceiver?
description. This octal bus transceiver is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.
What is data bus buffer?
In computer science, a data buffer (or just buffer) is a region of a memory used to temporarily store data while it is being moved from one place to another.
What is tri state buffer?
The Tri-state Buffer is used in many electronic and microprocessor circuits as they allow multiple logic devices to be connected to the same wire or bus without damage or loss of data.
What are bus buffers?
Definition: A three-state bus buffer is an integrated circuit that connects multiple data sources to a single bus. The open drivers can be selected to be either a logical high, a logical low, or high impedance which allows other buffers to drive the bus.
What is transceiver circuit?
In radio communication, a transceiver is an electronic device which is a combination of a radio transmitter and a receiver, hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes.
Why is buffering used?
Need of Buffering : It helps in matching speed between two devices, between which the data is transmitted. For example, a hard disk has to store the file received from the modem. It helps the devices with different data transfer size to get adapted to each other.
What is the difference between buffer and tri-state buffer?
A tri-state buffer is similar to a buffer, but it adds an additional “enable” input that controls whether the primary input is passed to its output or not. If the “enable” inputs signal is true, the tri-state buffer behaves like a normal buffer.
What is tri-state used for?
What is CMOS buffer?
CMOS buffer is formed by cascading two CMOS inverters back to back. Operation of one CMOS inverter is to invert the input signal to the opposite logic level. Thus a cascaded combination of two such circuits will bring back the input signal to the original level.
Why we use buffer instead of inverter?
In most of the library files, a buffer is the combination of two inverters so we can say that inverter will be having lesser delay than buffer with the same drive strength. Also inverters having more driving capacity than a buffer that’s why most of the libraries preferred inverter over buffer for CTS.
How do transceivers work?
Transceivers are wavelength-specific lasers that convert electrical data signals from data switches into optical signals. These signals can then be transmitted over the optical fiber. Each data stream is converted to a signal with a unique wavelength, meaning that it is effectively a unique light color.
Is a transceiver a switch?
Optical fiber transceiver is a relatively simple network hardware equipment, the interface is less than the switch, so its wiring and connection is relatively simple. They can be used alone or mounted in a rack.
Is cache same as buffer?
Buffer is an area of memory used to temporarily store data while it’s being moved from one place to another. Cache is a temporary storage area used to store frequently accessed data for rapid access.
Why tri-state buffers are used?
