General Description

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.

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.

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.

MAX4604/MAX4605/MAX4606 5Ω, Quad, SPST, CMOS Analog Switches Applications Information Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM.
