50 Ohm, Dual SPST Analog Switches in UCSP
General Description
The MAX4731/MAX4732/MAX4733 low-voltage, dual,
single-pole/single-throw (SPST) analog switches oper-
ate from a single +2V to +11V supply and handle rail-
to-rail analog signals. These switches exhibit low
leakage current (0.1nA) and consume less than 0.5nW
(typ) of quiescent power, making them ideal for battery-
powered applications.
When powered from a +3V supply, these switches fea-
ture 50Ω(max) on-resistance (RON) with 3.5Ω(max)
matching between channels, and 9Ω(max) flatness
over the specified signal range.
The MAX4731 has two normally open (NO) switches,
the MAX4732 has two normally closed (NC) switches,
and the MAX4733 has one NO and one NC switch. The
MAX4731/MAX4732/MAX4733 are available in 9-bump
chip-scale packages (UCSP™), along with 8-pin TDFN
and 8-pin µMAX®packages. The tiny UCSP occupies a
1.52mm ✕1.52mm area and significantly reduces the
required PC board area.

(Notes 3, 4)
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.

Note 1:Signals on IN_, NO_, NC_, or COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to
maximum current rating.
Note 2:This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device
can be exposed to during board level solder attach and rework. This limit permits only the use of the solder profiles recom-
mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection reflow. Pre-
heating is required. Hand or wave soldering is not allowed.

Applications Information
Operating Considerations for
High-Voltage Supply
The MAX4731/MAX4732/MAX4733 operate to +11V
with some precautions. The absolute maximum rating
for V+ is +12V (referenced to GND). When operating
near this region, bypass V+ with a minimum 0.1µF
capacitor to ground as close to the IC as possible.
Logic Levels
The MAX4731/MAX4732/MAX4733 are TTL compatible
when powered from a single +5V supply. When pow-
ered from other supply voltages, the logic inputs should
be driven rail-to-rail. For example, with a +11V supply,
IN1 and IN2 should be driven low to 0V and high to
11V. With a +3.3V supply, IN1 and IN2 should be dri-
ven low to 0V and high to 3.3V. Driving IN1 and IN2 rail-
to-rail minimizes power consumption.
