MAX4634EUB
Fast, Low-Voltage, 4з, 4-Channel CMOS Analog Multiplexer
General DescriptionThe MAX4634 fast, low-voltage, 4-channel CMOS ana-
log multiplexer features 4Ω(max) on-resistance (RON).
It offers RONmatching between switches to 0.3Ω(max)
and RONflatness of 1Ω(max) over the specified signal
range. Each switch can handle V+ to GND analog sig-
nals. Off-leakage current is only 0.1nA (max) at +25°C.
The MAX4634 features fast turn-on (tON) and turn-off
(tOFF) times of 18ns and 11ns, respectively. All this
comes in the tiny 10-pin µMAX and 10-pin, 3mm x 3mm,
thin QFN packages.
This low-voltage multiplexer operates from a +1.8V to
+5.5V single supply. All digital inputs have +0.8V and
+2.4V logic thresholds, ensuring TTL/CMOS-logic com-
patibility with +5V operation.

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:∆RON= RON(MAX)- RON(MIN).
Note 4:Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges.
Note 5:Guaranteed by design.
Note 6:Off-Isolation = 20log10(VCOM / VNO), where VCOM= output and VNO= input to off switch.
Note 7:Between any two switches.
Note 8:RONand ∆RON matching specifications for QFN-packaged parts are guaranteed by design.
Note 9:Thin QFN parts are tested at +25°C and guaranteed by design and correlation over the entire temperature range.
