General Description
The MAX4780/MAX4784 are low on-resistance, lowvoltage, quad 2:1 analog multiplexers that operate from
a single +1.6V to +4.2V supply. These devices have
fast switching speeds (tON= 20ns, t
OFF
= 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 0.7Ω on-resistance (RON), and
0.1Ω RONflatness. 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.

Detailed Description
The 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 0.7Ω R
ON
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.

Logic Inputs
The MAX4780/MAX4784 logic inputs can be driven up
to +4.2V regardless of the supply voltage. For example,
with a +1.8V supply, A_ and EN may be driven low to
GND and high to +4.2V. Driving A_ and EN rail-to-rail
minimizes power consumption. Drive EN low to enable
the COM_ outputs. When EN is high, the COM_ outputs
are high impedance.
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in on-
resistance (see the
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.

NOTES: MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT SOCKET TERMINALS.
OFF-ISOLATION IS MEASURED BETWEEN COM AND "OFF" NO TERMINAL ON EACH SWITCH.
ON-LOSS IS MEASURED BETWEEN COM AND "ON" NO TERMINAL ON EACH SWITCH.
CROSSTALK IS MEASURED FROM ONE CHANNEL TO ALL OTHER CHANNELS.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.
