High-Z Amplifier Output Capability  
Shutdown Capability  
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 connect-  
ed 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 MAX458/MAX459 are SPITM, QSPITM, and MicrowireTM  
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.
