MAX458中文资料8x4视频交叉点开关，带有缓冲器数据手册ADI规格书

描述 Description

The MAX458/MAX459 are crosspoint switches with eight input channels and four high-speed, buffered output channels. The MAX458 output buffer is configured with a gain of one, while the MAX459 buffer has a gain of two. In each device, any one of eight input lines can be connected to any of four output amplifiers. The output buffers are capable of driving loads of 75Ω.
Data interface can be accomplished by either a 16-bit serial or a 6-bit parallel connection. In the serial mode, the MAX458/MAX459 are SPI™, QSPI™, and Microwire™ compatible. In parallel mode, the MAX458/MAX459 are compatible with most microprocessor buses. Three-state amplifier output capability makes it possible to multiplex MAX458/MAX459s to form larger switch networks. The output buffers can be disabled individually or the entire device can be shut down to conserve power.

简介

MAX458属于集成电路（IC）的模拟开关多路复用器解复用器。由ADI制造生产的MAX458模拟开关，多路复用器，解复用器该系列产品可用于在多个可用信号路径之间互连或路由模拟信号。功能类似于传统的机电开关，但与机电开关相比，它们的固态特性有利于电子控制、延长使用寿命及降低开关噪声，但作为代价，切换信号的幅度和偏压限制有所增加。
