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.

簡介

MAX458屬于集成電路（IC）的模擬開關(guān)多路復(fù)用器解復(fù)用器。由制造生產(chǎn)的MAX458模擬開關(guān)，多路復(fù)用器，解復(fù)用器該系列產(chǎn)品可用于在多個可用信號路徑之間互連或路由模擬信號。功能類似于傳統(tǒng)的機電開關(guān)，但與機電開關(guān)相比，它們的固態(tài)特性有利于電子控制、延長使用壽命及降低開關(guān)噪聲，但作為代價，切換信號的幅度和偏壓限制有所增加。
