MAX4644EUA
High-Speed / Low-Voltage / 4 / SPDT CMOS Analog Switch
General DescriptionThe MAX4644 is a single-pole/double-throw (SPDT)
switch that operates from a single supply ranging from
+1.8V to +5.5V. It provides low 4Ωon-resistance (RON)
as well as 1ΩRONflatness over the entire analog signal
range. The MAX4644 offers fast switching times of less
than 20ns while ensuring break-before-make operation.
It typically consumes only 0.01µW of quiescent power,
making it suitable for use in low-power, portable appli-
cations.
The MAX4644’s features include low leakage currents
over the entire temperature range, TTL/CMOS-compati-
ble digital logic, and excellent AC characteristics. It is
packaged in either a small 8-pin µMAX or a tiny 6-pin
SOT23.

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 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 VCOMand VIis either VNCor VNOfrom the network analyzer.
Note 7:Crosstalk is measured between the two switches.

Pin Description
Note:The switches are bidirectional, which means that a signal can be passed through either side of the on switch. However,
the typical off-capacitances differ as shown in the Electrical Characteristics.
