2.5Ω, Quad, SPST,
CMOS Analog Switches
12/MAX463
General Description
Features
The MAX4661/MAX4662/MAX4663 quad 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. Off-

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 lower power require-
ments, use less board space, and are more reliable
than mechanical relays.
♦ Rail-to-Rail Signal Handling
♦ Guaranteed Break-Before-Make (MAX4663)
♦ > 2kV ESD Protection per Method 3015.7
♦ +4.5V to +36V Single-Supply Operation
The MAX4661 has four normally closed (NC) switches,
and the MAX4662 has four normally open (NO) switches.
The MAX4663 has two NC and two NO switches, and fea-
tures guaranteed break-before-make switching.
±4.5V to ±20V Dual-Supply Operation
♦ TTL/CMOS-Compatible Control Inputs
These devices operate from a single +4.5V to +36V sup-
ply or from dual 4.5V to 20V supplies. A separate logic
supply pin guarantees TTL/CMOS-logic compatibility
when operating across the entire supply voltage range.
