MAX459

8x4 Video Crosspoint Switches with Buffers


Please check latest availability status for a specific part variant.

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.
