General Description
The MAX4571–MAX4574 serial-interface controlled
switches are ideal for multimedia applications. Each
device features 35Ωmax 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 2:The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3:Guaranteed by design. Not subject to production testing.
Note 4:ΔRON= RON(MAX)- RON(MIN).
Note 5:Resistance flatness is defined as the difference between the maximum and minimum on-resistance values, as measured
over the specified analog signal range.
Note 6:Leakage parameters are 100% tested at maximum rated temperature, and guaranteed by correlation at TA= +25°C.
Note 7:Off-isolation = 20 log [VCOM_ / VNO_ _ ], VCOM_ = output, VNO_ _ = input to off switch.
Note 8:All timing is measured from the rising clock edge of the ACK bit for 2-wire, and from the rising edge of CSfor 3-wire. Turn-
off time is defined at the output of the switch for a 0.5V change, tested with a 300Ωload to ground. Turn-on time is mea-
sured with a 5kΩload resistor to GND. All timing is shown with respect to 20% V+ and 70% V+, unless otherwise noted.
Note 9:Supply current can be as high as 2mA per switch during switch transitions in the clickless mode, corresponding to a 28mA
total supply transient current requirement.
Note 10:Leakage testing for single-supply operation is guaranteed by testing with a single +5.25V supply.
Note 11:Cb= capacitance of one bus line in pF. Tested with Cb= 400pF.
Note 12:Typical values are for MAX4573/MAX4574 devices.21345
