Abstract: Buffer is one kind of digital components. It can make the work of the high-speed CPU and peripheral slow work coordination and buffer role, realizes the data transmission synchronization.
Buffer is one kind of digital components, it does not perform any operations on the input value, the output value and input values, but it plays an important role in the design of the computer.
Buffer is divided into two kinds, the conventional buffer (often said buffer) and tri-state buffers. The conventional buffer will always value directly output, use in advancing the current to the high level of the circuit system. Tri-state buffers in addition to the function of the conventional buffer, there are a cartoon input options, expressed in E. When E = 0 and E = 1 has different output values.
When the E = 1, time, its input directly to the output;
If E = 0, buffer be stopped, no matter what input values, the output is high impedance state, represented by Z. High resistance state can cause the current to a low enough, so that as the output of the buffer is not connected to anything.
Buffer includes shell and installed in the casing of the resilient rubber energy-absorbing component, one end of the shell equipped with a clamp, the clamp beforehand and resilient rubber energy absorption components with shell part of the elastic contact, the outer edge and a connection board in the process of the pressure plate is even, highlight the outside edge of the shell in advance between the clamp and the connecting plate, the buffer between connected to highlight the outer edge of plate and shell with embedded block. Precompression structure buffer compress energy absorption components make buffer structure size smaller. When installation without further compression, which can be installed directly, simplifies the installation process, improved the working conditions of workers. Still sliding inside the installation seat adjusts the buffer settings have the pull rod. Tie rod end into the buffer, out the other end of the installation set connected to the regulating mechanism. Fixed way to furniture plate clamps connection method, achieve rapid installation. Its structure is the simple reason, adjustment precision large, easy installation and removal, applicable to a wide range.
