General Description
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.
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.
These switches operate from a single +4.5V to +36V
supply or from dual ±4.5V to ±20V supplies. All digital
inputs have +0.8V and +2.4V logic thresholds, ensuring
TTL/CMOS-logic compatibility when using ±15V sup-
plies or a single +12V 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.
