5Ω, Quad, SPST, CMOS Analog Switches
5/MAX406
General Description
Features
The MAX4604/MAX4605/MAX4606 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 2.5nA 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. These switches have low power requirements,
require less board space, and are more reliable than
mechanical relays.

♦ Rail-to-Rail Signal Handling
♦ Guaranteed ESD Protection > 2000V per
Method 3015.7
♦ Single-Supply Operation: +4.5V to +36V
The MAX4604 has four normally closed (NC) switches,
the MAX4605 has four normally open (NO) switches,
and the MAX4606 has two NC and two NO switches.
Dual-Supply Operation: ±4.5V to ±20V
♦ TTL/CMOS-Compatible Control Inputs
These switches operate from a single supply of +4.5V
to +36V or from dual supplies of ±4.5V to ±20V. All dig-
ital inputs have +0.8V and +2.4V logic thresholds,
ensuring TTL/CMOS logic compatibility when using
±15V supplies or a single +12V supply.
