0.7 M Low-Voltage, Quad 2:1 Analog Multiplexers
19-2365; Rev 3; 12/04
General DescriptionThe MAX4780/MAX4784 are low on-resistance, low-
voltage, quad 2:1 analog multiplexers that operate from
a single +1.6V to +4.2V supply. These devices have
fast switching speeds (tON= 20ns, tOFF= 8ns), handle
rail-to-rail analog signals, and consume less than 1µW
of quiescent power.
When powered from a +2.7V supply, the MAX4780/
MAX4784 feature low 0.7Ωon-resistance (RON), and
0.1ΩRONflatness. The digital logic input is +1.8V
CMOS-logic compatible when using a single +3V supply.
The MAX4780/MAX4784 are available in 16-pin TSSOP
and 3mm x 3mm thin QFN packages.

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 COM_, NO_, or NC_ exceeding V+ or GND are clamped by internal diodes. Limit forward current to maximum
current rating.

Note 2:The algebraic convention, where the most negative value is a minimum and the most positive value is a maximum, is
used in this data sheet.

Note 8:Guaranteed by design.

Note 10:Between two switches.
Note 11:Parts are guaranteed to 1 million cycles of operation. (Cycle = switch on →switch off →switch on.)
Note 12:The minimum load resistance is 8Ω. (See the Typical Application Circuit.)

Detailed DescriptionThe MAX4780/MAX4784 are low 0.7Ω(at V+ = +2.7V)
on-resistance, low-voltage, quad 2:1 analog multiplexers/
demultiplexers that operate from a +1.6V to +4.2V single
supply. CMOS switch construction allows switching
analog signals that are within the supply voltage range
(GND to V+).
When powered from a +2.7V supply, the 0.7ΩRON
allows high continuous currents to be switched in a
variety of applications.
Applications InformationProper 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.
