_______________General Description
The MAX4521/MAX4522/MAX4523 are quad, low-voltage, single-pole/single-throw (SPST) analog switches.
On-resistance (100Ω max) is matched between switches to 4Ω max, and is flat (12Ω max) over the specified
signal range. Each switch can handle rail-to-rail analog
signals. The off-leakage current is only 1nA at +25°C
and 10nA at +85°C.
The MAX4521 has four normally closed (NC) switches,
and the MAX4522 has four normally open (NO) switches. The MAX4523 has two NC switches and two NO
switches.
These CMOS switches can operate with dual power
supplies ranging from ±2V to ±6V or a single supply
between +2V and +12V. They are fully specified for single +2.7V operation.
All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when
using ±5V or a single +5V supply.

, unless otherwise noted. Typical values are at TA= +25°C.)
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.
Note 2: All leads are soldered or welded to PC boards.
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.
