MAXIM MAX4741EUA

19-2116; Rev 2; 12/06
0.8Ω, Low-Voltage, Single-Supply Dual SPST
Analog Switches
Features
The MAX4741/MAX4742/MAX4743 are low on-resistance,
low-voltage, dual single-pole/single-throw (SPST) analog
switches that operate from a single +1.6V to +3.6V supply. These devices have fast switching speeds (tON =
24ns, tOFF = 16ns max), handle rail-to-rail analog signals,
and consume less than 1µW of quiescent power. The
MAX4743 has break-before-make switching.
When powered from a +3V supply, the MAX4741/
MAX4742/MAX4743 feature low 0.8Ω (max) on-resistance (R ON ), with 0.08Ω (max) R ON matching and
0.18Ω R ON flatness. The digital logic input is 1.8V
CMOS compatible when using a single +3V supply.
♦ Low RON:
0.8Ω max (+3V Supply)
2.5Ω max (+1.8V Supply)
The MAX4741 has two normally open (NO) switches,
the MAX4742 has two normally closed (NC) switches,
and the MAX4743 has one NO switch and one NC
switch. The MAX4741 is available in 8-pin µDFN (2mm
x 2mm), 8-pin SOT23, and 8-pin µMAX® packages. The
MAX4742/MAX4743 are available in 8-pin SOT23 and
8-pin µMAX packages.
♦ Fast Switching: tON = 24ns, tOFF = 16ns
♦ 0.18Ω max RON Flatness (+3V Supply)
♦ +1.6V to +3.6V Single-Supply Operation
♦ Available in SOT23 and µMAX Packages
♦ High-Current Handling Capacity (150mA
continuous)
♦ 1.8V CMOS Logic Compatible (+3V Supply)

Detailed Description
The MAX4741/MAX4742/MAX4743 are low 0.8Ω max
(at V+ = +3V) on-resistance, low-voltage, dual analog
switches that operate from a +1.6V to +3.6V single supply. CMOS switch construction allows switching analog
signals that are within the supply voltage range (GND
to V+).
When powered from a +3V supply, the 0.8Ω max RON
allows high continuous currents to be switched in a
variety of applications.
Applications Information
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, followed by NO_, NC_, or
COM_.
Although it is not required, power-supply bypassing
improves noise margin and prevents switching noise
propagation from the V+ supply to other components.
A 0.1µF capacitor, connected from V+ to GND, is adequate for most applications.
Analog Switch 2 Normally Closed
Analog Switch 2 Common
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in onresistance (see Typical Operating Characteristics). The
switches are bidirectional, so the NO_, NC_, and COM_
pins can be used as either inputs or outputs.
Layout
High-speed switches require proper layout and design
procedures for optimum performance. Reduce stray
inductance and capacitance by keeping traces short
and wide. Ensure that bypass capacitors are as close
to the device as possible. Use large ground planes
where possible.
Logic Inputs
The MAX4741/MAX4742/MAX4743 logic inputs can be
driven up to +3.6V regardless of the supply voltage.
For example, with a +1.8V supply, IN_ may be driven
low to GND and high to +3.6V. Driving IN_ rail-to-rail
minimizes power consumption.
