8x4 Video Crosspoint Switches with Buffers
_______________General 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 SPITM, QSPITM, and MicrowireTM compatible. In parallel mode, the MAX458/MAX459 are compatible with most microprocessor buses.
