3V/5V / 4 / Wideband Quad 2:1 Analog Multiplexer
General DescriptionThe MAX4674 is a low-voltage CMOS analog switch con-
taining four 2:1 multiplexers/demultiplexer. When pow-
ered from a single +5V supply, it features a low 4Ωmax
on-resistance (RON), 0.4Ωmax RONmatching between
channels, and 0.8ΩRON flatness over the entire signal
range. Off-leakage current is only 0.5nA max at +25°C.
The MAX4674 features fast turn-on (tON) and turn-off
(tOFF) times of 18ns and 6ns, respectively, and is avail-
able in QFN, QSOP, TSSOP, and SO packages.
This low-voltage multiplexer operates with a +1.8V to
+5.5V single supply. All digital inputs have +0.8V and
+2.4V logic thresholds, ensuring TTL/CMOS-logic com-
patibility with +5V operation.

MAX4674
3V/5V, 4Ω, Wideband Quad
2:1 Analog Multiplexer
Detailed DescriptionThe MAX4674 is a low on-resistance (RON), low-volt-
age, quad 2:1 analog multiplexer/demultiplexer that
operates from a +1.8V to +5.5V single supply. The
MAX4674 features very fast switching speed (tON=
18ns max, tOFF= 6ns max) and guaranteed break-
before-make switching. Its low RONallows high continu-
ous currents to be switched in a variety of applications.
Digital InterfaceA0 and ENare CMOS digital inputs that meet TTL logic
levels when V+ = 5V. Note that A0 and ENcan exceed
the voltage at V+ to a maximum of +5.5V. This feature
allows operation of the MAX4674 from a +3.3V supply
while controlling it with 5V CMOS logic signals.
The Pin Configuration/Functional Diagram/Truth Table
located on the first page of this data sheet details the
operation of the MAX4674.
Applications Information
Power-Supply Considerations
OverviewThe MAX4674 construction is typical of most CMOS
analog switches. It has two supply pins, V+ and GND,
used to drive the internal CMOS switches and set the
limits of the analog voltage on any switches. Reverse
ESD-protection diodes are internally connected
between each analog-signal pin and both V+ and
GND. If any analog signal exceeds V+ and GND, one
of these diodes conducts. During normal operation,
these and other reverse-biased ESD diodes leak, form-
ing 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 pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by
either V+ or GND and the analog signal. This means
their leakages will vary as the signal varies. The differ-
ence in the two-diode leakages to the V+ and GND
pins constitutes the analog-signal-path leakage current.
All analog leakage current flows between each pin and
one of the supply terminals, not to the other switch ter-
minal, which is why both sides of a given switch can
show leakage currents of either the same or opposite
polarity.
V+ and GND power the internal logic and set the input
logic limits. Logic inputs have ESD-protection diodes to
ground.
The logic-level thresholds are TTL/CMOS compatible
when V+ is +5V. As V+ rises, the threshold increases;
as V+ falls, the threshold decreases. For example,
MAX4674
3V/5V, 4Ω, Wideband Quad
2:1 Analog Multiplexerwhen V+ = +3V, the guaranteed minimum logic-high
threshold decreases to 2.0V.
Low-Voltage OperationThe MAX4674 operates from a single supply between
+1.8V and +5.5V. At room temperature, it actually
“works” with a single supply near or below +1.7V; as
supply voltage decreases, however, switch on-resis-
tance becomes very high.
Overvoltage ProtectionProper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings because stresses beyond the listed rat-
ings can cause permanent damage to the device.
Always sequence V+ on first, followed by the logic
inputs and analog signals. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with the supply pins for overvoltage protection
(Figure 1).
Adding diodes reduces the analog-signal range to one
diode drop below V+ and one diode drop above GND,
but does not affect the device’s low switch resistance
and low leakage characteristics. Device operation is
unchanged, and the difference between V+ and GND
should not exceed 6V. These protection diodes are not
recommended if signal levels must extend to ground.
High-Frequency PerformanceIn 50Ωsystems, signal response is reasonably flat up
to 50MHz (see Typical Operating Characteristics).
Above 20MHz, the on response has several minor
peaks that are highly layout dependent. The problem is
not turning the switch on, but turning it off. The off-state
switch acts like a capacitor and passes higher frequen-
cies with less attenuation. At 10MHz, off-isolation is
about -50dB in 50Ωsystems, becoming worse (approx-
imately 20dB per decade) as frequency increases.
Higher circuit impedances also degrade off-isolation.
Adjacent channel attenuation is about 3dB above that
of a bare IC socket and is entirely due to capacitive
coupling.
