Serially Controlled
Audio/Video Switches
General Description
The MAX4584/MAX4585 serial-interface, programmable
switches are ideal for multimedia applications. Each
device contains one normally open (NO) single-pole/
single-throw (SPST) switch and one single-pole/double-
throw (SPDT) switch. The MAX4584/MAX4585 feature
65Ω on-resistance, 4Ω on-resistance matching
between channels, and 5Ω on-resistance flatness.
Additionally, they have off-isolation of -83dB at 20kHz
and -48dB at 10MHz, with crosstalk of -84dB at 20kHz
and -60dB at 10MHz.
The MAX4584 uses a 2-wire I²C™-compatible serial
interface; the MAX4585 uses a 3-wire SPI™/QSPI™/
MICROWIRE™-compatible interface. Both devices are
available in a 10-pin µMAX package and are specified
for the extended-industrial (-40°C to +85°C) temperature
range.
