MAX4780 Datasheet, PDF (1/13 Pages) Maxim Integrated Products – 0.7 M Low-Voltage, Quad 2:1 Analog Multiplexers

19-2365; Rev 3; 12/04
0.7Ω, Low-Voltage, Quad 2:1 Analog
Multiplexers
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.
