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.
