General Description
The MAX4781/MAX4782/MAX4783 are high-speed,
low-voltage, low on-resistance, CMOS analog multiplex-
ers/switches configured as an 8-channel multiplexer
(MAX4781), two 4-channel multiplexers (MAX4782),
and three single-pole/double-throw (SPDT) switches
(MAX4783).
These devices operate with a +1.6V to +3.6V single
supply. When powered from a +3V supply, MAX4781/
MAX4782/MAX4783 feature a 0.7Ωon-resistance
(RON), with 0.3ΩRONmatching between channels, and
0.1ΩRONflatness. These devices handle rail-to-rail
analog signals while consuming less than 3µW of qui-
escent power. They are available in space-saving 16-
pin thin QFN (3mm x 3mm) and TSSOP packages.

Applications Information
Power-Supply Considerations
Overview
The MAX4781/MAX4782/MAX4783 construction is typical
of most CMOS analog switches. There are two supply
inputs: VCCand GND. VCCand GND drive the internal
CMOS switches and set the limits of the analog voltage
on any switch. Internal reverse ESD-protection diodes are
connected between each analog signal input and both
VCCand GND. If any analog signal exceeds VCCor
GND, one of these diodes conducts. During normal oper-
ation, these and other reverse-biased ESD diodes leak,
forming the only current drawn from VCCor GND.
Virtually all the analog leakage current comes from the
ESD diodes. Although the ESD diodes on a given sig-
nal input are identical and therefore fairly well bal-
anced, they are reverse-biased differently. Each diode
is biased by either VCCor GND and the analog signal.
Their leakages vary as the signal varies. The difference
in the two diodes’ leakages to VCCand GND consti-
tutes the analog-signal-path leakage current. All analog
leakage current flows between each input and one of
the supply terminals, not to the other switch terminal.
Both sides of a given switch can show leakage currents
of either the same or opposite polarity.
VCCand GND power the internal logic and set the input
logic limits. Logic inputs have ESD-protection diodes
to ground.
Power Supply
The MAX4781/MAX4782/MAX4783 operate from a sin-
gle supply between +1.6V and +3.6V. Switch on-resis-
tance increases as the supply voltage is lowered.
High-Frequency Performance
In 50Ωsystems, signal response is reasonably flat up
to 50MHz (see the Typical Operating Characteristics).
Above 20MHz, the on-response has several minor
peaks that are highly layout dependent. In the off state,
the switch acts like a capacitor and passes higher fre-
quencies with less attenuation. At 10MHz, off-isolation
is approximately -50dB in 50Ωsystems, becoming
worse (approximately 20dB per decade) as frequency
increases. Higher circuit impedance also degrades off-
isolation. Adjacent channel attenuation is approximate-
ly 3dB above that of a bare IC socket and is entirely
because of capacitive coupling.
Pin Nomenclature
The MAX4781/MAX4782/MAX4783 are pin compatible
with the industry-standard 74HC4051/74HC4052/
74HC4053 and the MAX4617/MAX4618/MAX4619. In
single-supply applications, they function identically and
have identical logic diagrams, although these parts dif-
fer electrically. The pin designations and logic dia-
grams in this data sheet conform to the original 1972
specifications published by RCA for the CD4051/
CD4052/CD4053. These designations differ from the
standard Maxim switch and mux designations found on
other Maxim data sheets such as the MAX4051/
MAX4052/MAX4053. Designers who are more comfort-
able with Maxim’s standard designations are advised
that the pin designations and logic diagrams on the
MAX4051/MAX4052/MAX4053 data sheet can be
applied to the MAX4781/MAX4782/MAX4783.
