5/MAX46
General Description
Features
The MAX4664/MAX4665/MAX4666 quad analog switch-
es feature 5Ω max on-resistance. 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 cur-
rent is only 5nA max at +85°C. These analog switches
are ideal in low-distortion applications and are the pre-
ferred solution over mechanical relays in automatic test
equipment or in applications where current switching is
required. They have low power requirements, require
less board space, and are more reliable than mechanical
relays.

♦ Guaranteed ESD Protection > 2kV per
Method 3015.7
The MAX4664 has four normally closed (NC) switches,
the MAX4665 has four normally open (NO) switches, and
the MAX4666 has two NC and two NO switches that
guarantee break-before-make switching times.
♦ +4.5V to +36V Single-Supply Operation
±4.5V to ±20V Dual-Supply Operation
♦ TTL/CMOS-Compatible Control Inputs
These switches operate from a single +4.5V to +36V
supply or from dual ±4.5V to ±ꢀ0V supplies. All digital
inputs have +0.8V and +ꢀ.4V logic thresholds, ensuring
TTL/CMOS-logic compatibility when using ±±5V sup-
plies or a single +±ꢀV supply.

Note 1: Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- are clamped by internal diodes. Limit 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.

Overvoltage Protection

Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings, because stresses beyond the listed rat-
ings 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 (D±, Dꢀ) in
series with supply pins (Figure ±). 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 leak-
age characteristics. Device operation is unchanged,
and the difference between V+ and V- should not
exceed 44V. These protection diodes are not recom-
mended when using a single supply.

Off-Isolation at High Frequencies
In 50Ω systems, the high-frequency on-response of
these parts extends from DC to above ±00MHz, with a
typical loss of -ꢀdB. When the switch is turned off, how-
ever, 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.

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 criti-
cal applications above 5MHz, use the MAX440,
MAX44±, and MAX44ꢀ, which are fully characterized
up to ±60MHz.
