Analog Video Crosspoint 90MHz 8 x 4 40-Pin PDIP

The MAX459 are cross point 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 75?. Data interface can be accomplished by either a 16-bit serial or a 6-bit parallel connection. In the serial mode, the MAX459 are SPITM, QSPITM, and Micro wireTM compatible. In parallel mode, the MAX459 are compatible with most microprocessor buses. Three-state amplifier output capability makes it possible to multiplex MAX459s to form larger switch networks. The output buffers can be disabled individually or the entire device can be shut down to conserve power.
