MAX4572
19-1404; Rev 1; 4/99
Serially Controlled, Clickless
Audio/Video Switches
General Description
The MAX4571–MAX4574 serial-interface controlled
switches are ideal for multimedia applications. Each
device features 35max on-resistance, -90dB audio
off-isolation at 20kHz, -60dB video off-isolation at
1.0MHz, and “clickless” mode operation for audio
applications.
The MAX4571/MAX4573 contain eleven SPST switches,
while the MAX4572/MAX4574 contain two SPST switch-
es and six SPDT switches. The MAX4571/MAX4572 fea-
ture a 2-wire, I2C™-compatible serial interface. The
MAX4573/MAX4574 feature a 3-wire, SPI™/QSPI™/
MICROWIRE™-compatible serial interface. All four
parts are available in 28-pin QSOP, SSOP, and wide
SO packages and operate over the commercial and
extended temperature ranges.

Note 1: Signals on NO_ _ or COM_ exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum
current rating.
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.
