General Description
The MAX458/MAX459CQH 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 MAX459CQH 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/MAX459CQH are SPITM, QSPITM, and MicrowireTM compatible. In parallel mode, the MAX458/MAX459CQH 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.
