Low-Voltage, Single-Supply
Dual SPST/SPDT Analog Switches
General Description ____________________________Features
The MAX4541–MAX4544 are precision, dual analog
switches designed to operate from a single +2.7V to
+12V supply. Low power consumption (5µW) makes
these parts ideal for battery-powered equipment. These
switches offer low leakage currents (100pA max) and fast
switching speeds (tON = 150ns max, tOFF = 100ns max).
When powered from a +5V supply, the MAX4541–
MAX4544 offer 2max matching between channels, 60
max on-resistance (RON), and 6max RON flatness.
These switches also offer 5pC max charge injection and
a minimum of 2000V ESD protection per Method 3015.7.
The MAX4541/MAX4542/MAX4543 are dual single-pole/
single-throw (SPST) devices and the MAX4544 is a single-
pole/double-throw (SPDT) device. The MAX4541 has two
normally open (NO) switches and the MAX4542 has two
normally closed (NC) switches. The MAX4543 has one NO
and one NC switch and can be used as an SPDT, while
the MAX4544 is an SPDT. The MAX4541/MAX4542/
MAX4543 are available in tiny SOT23-8 packages, and
the MAX4544 is available in a SOT23-6 package.

Applications Information
Logic Levels
The MAX4541–MAX4544 are TTL compatible when
powered from a single +5V supply. When powered
from other supply voltages, TTL compatibility is guar-
anteed and the logic inputs can be driven Rail-to-Rail®.
For example, with a +12V supply, IN1 and IN2 can be
driven low to 0 and high to 12V. With a +3.3V supply,
IN1 and IN2 should be driven low to 0 and high to
3.3V.
Driving IN1 and IN2 rail-to-rail minimizes power con-
sumption.
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be switched with very little change in
on-resistance over the entire voltage range (see Typical
Operating Characteristics). All the switches are bidirec-
tional, so the NO_, NC_, and COM_ pins can be used
as either inputs or outputs.
