MAX4641EUA
High-Speed / Low-Voltage / 4 / Dual SPST CMOS Analog Switches
General DescriptionThe MAX4641/MAX4642/MAX4643 are monolithic, dual,
single-pole/single-throw (SPST) switches that can operate
from a single supply ranging from +1.8V to +5.5V. The
MAX4641/MAX4642/MAX4643 provide low 4Ωon-resis-
tance (RON), 0.6ΩRONmatching between channels, andRONflatness over the entire analog signal range.
These devices offer fast switching times of less than 20ns
while consuming less than 0.01µW of quiescent power.
The MAX4641 has two normally open (NO) switches,
and the MAX4642 has two normally closed (NC)
switches. The MAX4643 has one NO switch and one NC
switch. All three devices have low 0.35nA leakage cur-
rents over the entire temperature range. The MAX4641/
MAX4642/MAX4643 are available in small 8-pin µMAX
and 8-pin QFN packages.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS—Single +5V Supply(V+ = +4.5V to +5.5V, VINH= 2.4V, VINL= 0.8V, TA= TMINto TMAX, unless otherwise noted. Typical values are at TA= +25°C.)
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:∆RON= RON(MAX)- RON(MIN).
Note 3:RONFlatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 4:Guaranteed by design.
Note 5:On-Leakage performed with voltage applied to COM_, with NO_ and NC_ left floating.
Note 6:Off-Isolation = 20log10(VO_ / VI_), where VOis VCOM_and VIis VNC_or VNO_from the network analyzer.
Note 7:Crosstalk is measured between the two switches.
Note 8:RONand ∆RONmatching specifications for QFN-packaged parts are guaranteed by design.

Pin Description
Note:NO_, NC_, and COM_ pins are identical and interchangeable. Signals can be passed through either side of these bidirectional
switches. However, the typical off-capacitances differ, as shown in the Electrical Characteristics.
