_______________General Desc ription
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 SPI
TM
, QSPI
TM
, and Microwire
TM
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.
