MAX4784EUE+T

P1-P3P4-P6P7-P9P10-P11
19-2365; Rev 4; 3/09
General Description
The 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 (t
ON
= 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 (R
ON
), and
0.1Ω R
ON
flatness. 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.
