Serially Controlled, Dual 4x2, Clickless Audio/Video Analog Crosspoint Switches
General DescriptionThe MAX4550/MAX4570 serial-interface, programma-
ble, dual 4x2 audio/video crosspoint switches are ideal
for multimedia applications. Each device contains two
identical crosspoint switch arrays, each with four inputs
and two outputs. To improve off-isolation, use the addi-
tional crosspoint inputs SA and SB as shunts. Each out-
put is selectively programmable for clickless or regular
mode operation. A set of internal resistive voltage-
dividers supplies DC bias for each output when using
AC-coupled inputs. Additionally, four auxiliary outputs
control additional circuitry via the MAX4550/MAX4570’s
2-wire or 3-wire interface.
The MAX4550/MAX4570 feature 80Ωon-resistance, 10Ω
on-resistance matching between channels, 5Ωon-
resistance flatness, and 0.014% total harmonic distor-
tion. Additionally, they feature off-isolation of at least
-110dB in the audio frequency range and -78dB at
4MHz, with -95dB crosstalk in the audio frequency
range and -54dB at 4MHz. The MAX4550 uses a 2-wire2C-compatible serial interface, while the MAX4570
uses a 3-wire SPI™/QSPI™ or MICROWIRE™-compati-
ble serial interface. These parts are available in 28-pin
SSOP and wide SO packages and are tested over
either the commercial (0°C to +70°C) or extended
(-40°C to +85°C) operating temperature range.

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

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:On-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 clock’s falling edge preceding the ACK signal for 2-wire, and from CS’s rising edge for
3-wire. Turn-Off Time is defined as the output of the switch for 0.5V change, tested with a 300Ωload to ground. Turn-On
Time is measured with a 5kΩload resistor to GND. All timing is shown with respect to 20% of V+ and 70% of V+, unless
otherwise noted.
Note 9:Typical values are for MAX4570 only.
Note 10:Supply current can be as high as 2mA per switch during switch transitions in the clickless mode, corresponding to 40mA
total supply transient current requirement.
Note 11:Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
Note 12:Cb = capacitance of one bus line in pF. Tested with Cb = 400pF.-3-2-1-4012435
