ELECTRICAL CHARACTERISTICS
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: Outputs may be shorted to any supply pin or ground as long as package power dissipation ratings are not exceeded.

The MAX458CQH is crosspoint switches with eight input channels and four high-speed, buffered output channels. The MAX458CQH 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 MAX458CQH is SPITM, QSPITM, and MicrowireTM compatible. In parallel mode, the MAX458CQH/MAX459 are compatible with most microprocessor buses. Three-state amplifier output capability makes it possible to multiplex MAX458/MAX459s to form larger switch net works. The output buffers can be disabled individually or the entire device can be shut down to conserve power.
