MAX4734 Datasheet, PDF (1/11 Pages) Maxim Integrated Products – 0.8Ω, Low-Voltage, 4-Channel Analog Multiplexer

19-2381; Rev 0; 4/02
0.8Ω, Low-Voltage, 4-Channel
Analog Multiplexer
General Description
The MAX4734 is a low on-resistance, low-voltage, 4-
channel CMOS analog multiplexer that operates from a
single 1.6V to 3.6V supply. This device has fast switch-
ing speeds (t_ON = 25ns, t_OFF = 20ns max), handles
Rail-to-Rail^® analog signals, and consumes less than
4µW of quiescent power. The MAX4734 has break-
before-make switching.
When powered from a 3V supply, the MAX4734 fea-
tures low 0.8Ω (max) on-resistance (R_ON), with 0.2Ω
(max) R_ON matching and 0.1Ω R_ON flatness. The digital
logic input is 1.8V CMOS compatible when using a sin-
gle 3V supply.
The MAX4734 is available in space-saving 12-pin QFN
(3mm x 3mm) and 10-pin µMAX packages.
