2.5Ω, Dual, SPST,
CMOS Analog Switches
Features
The MAX4667/MAX4668/MAX4669 dual analog switches
feature low on-resistance of 2.5Ω max. On-resistance is
matched between switches to 0.5Ω max and is flat (0.5Ω
max) over the specified signal range. Each switch can
handle Rail-to-Rail® analog signals. The off-leakage current is only 5nA max at +85°C. These analog switches
are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test
equipment or applications where current switching is
required. They have low power requirements, use less
board space, and are more reliable than mechanical
relays.
The MAX4667 has two normally closed (NC) switches,
the MAX4668 has two normally open (NO) switches,
and the MAX4669 has one NC and one NO switch that
guarantee break-before-make operation.
These switches operate from a +4.5V to +36V single
supply or from ±4.5V to ±20V dual supplies. All digital
inputs have +0.8V and +2.4V logic thresholds, ensuring
TTL/CMOS-logic compatibility when using ±15V supplies or a single +12V supply.
♦ Low On-Resistance (2.5Ω max)
♦ Guaranteed RON Match Between Channels
(0.5Ω max)
♦ Guaranteed RON Flatness over Specified Signal
Range (0.5Ω max)
♦ Guaranteed Break-Before-Make (MAX4669)
♦ Rail-to-Rail Signal Handling
♦ Guaranteed ESD Protection >2kV
per Method 3015.7
♦ +4.5V to +36V Single-Supply Operation
±4.5V to ±20V Dual-Supply Operation
♦ TTL/CMOS-Compatible Control Inputs

Note 1: Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- will be clamped by internal diodes. Limit the forward diode current to
maximum current rating.
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: Guaranteed by design.
Note 4: ∆RON = RON(MAX) - RON(MIN).
Note 5: Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the
specified analog signal range.
Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at +25°C.
Note 7: Off-isolation = 20log10 [VCOM / (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch.
Note 8: Between any two switches.
Note 9: Leakage testing at single supply is guaranteed by testing with dual supplies.

Applications Information
Overvoltage Protection
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs, NO, or COM. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with supply pins (Figure 1). Adding diodes
reduces the analog signal range to one diode drop
below V+ and one diode drop above V-, but does not
affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged,
and the difference between V+ and V- should not
exceed 44V. These protection diodes are not recommended when using a single supply.
Off-Isolation at High Frequencies
With the N.C. pins connected to GND, the high-frequency on-response of these parts extends from DC to
above 100MHz with a typical loss of -2dB. When the
switch is turned off, however, it behaves like a capacitor, and off-isolation decreases with increasing frequency. (Above 300MHz, the switch actually passes more
signal turned off than turned on.) This effect is more
pronounced with higher source and load impedances.

FUNCTION
MAX4667
No Connection. Not internally connected. Connect to GND as
low impedance to improve on/off-isolation.
Logic-Control Digital Inputs
Negative Analog Supply Voltage Input. Connect to GND for
single-supply operation.
Ground
Analog Switch, Common Terminals
Above 5MHz, circuit-board layout becomes critical and
it becomes difficult to characterize the response of the
switch independent of the circuit. The graphs shown in
the Typical Operating Characteristics were taken using
a 50Ω source and load connected with BNC connectors
to a circuit board deemed “average”; that is, designed
with isolation in mind, but not using stripline or other
special RF circuit techniques. For critical applications
above 5MHz, use the MAX440, MAX441, and MAX442,
which are fully characterized up to 160MHz.
