Fast, Low-Voltage, Dual 4Ω SPDT CMOS Analog Switches
General DescriptionThe MAX4635/MAX4636 are fast, dual 4Ωsingle-
pole/double-throw (SPDT) analog switches that operate
with supply voltages from +1.8V to +5.5V. High switch-
ing speeds, 1Ωon-resistance flatness, and low power
consumption make these devices ideal for audio/video,
communications, and battery-operated devices.
Containing two independently controllable SPDT
switches in 10-pin µMAX and 10-pin 3mm x 3mm thin
QFN packages, the MAX4635/MAX4636 use little board
space, and have low power consumption ensuring min-
imal impact on your power budget. The analog signal
range extends to the supply rails. The MAX4635 has
inverted logic compared to the MAX4636.

(Notes 2, 9)
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 2:The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 3:ΔRON= RON(MAX)- RON(MIN).
Note 4:ΔRONmatching specifications for QFN-packaged parts are guaranteed by design.
Note 5:Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the
specified analog signal ranges.
Note 6:Guaranteed by design.
