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.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS—Single +5V Supply

(V+ = +5V ±5%, TA= TMINto TMAX, unless otherwise noted. Typical values are at TA= +25°C.) (Note 2)
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.
V+ to GND................................................................-0.3V to +6V
NO_ _, COM_, DOUT to GND (Note 1)........-0.3V to (V+ + 0.3V)
SCL, SDA, CS, SCLK, DIN, A0, A1 to GND..............-0.3V to +6V
Continuous Current into Any Terminal..............................±10mA
Peak Current (pulsed at 1ms, 10% duty cycle)................±50mA
Continuous Power Dissipation (TA= +70°C)
QSOP (derate 10.8mW/°C above +70°C)...................860mW
SSOP (derate 9.5mW/°C above +70°C).....................762mW
Wide SO (derate 12.5mW/°C above +70°C).............1000mW
Operating Temperature Ranges
MAX457_C_ _....................................................0°C to +70°C
MAX457_E_ _..................................................-40°C to +85°C
Storage Temperature Range.............................-65°C to +160°C
Lead Temperature (soldering, 10sec).............................+300°C
Note 1:
Signals on NO_ _ or COM_ exceeding V+ or V- are clamped by internal diodes. Limit forward-diode current to maximum
current rating.

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.
