3.5Ω, Single 8:1 and Dual 4:1,
Low-Voltage Analog Multiplexers
General DescriptionThe MAX4638/MAX4639 are single 8:1 and dual 4:1
CMOS analog multiplexers/demultiplexers (muxes/
demuxes). Each mux operates from a single +1.8V to
+5V supply or dual ±2.5V supplies. These devices fea-
ture 3.5Ωon-resistance (RON) when powered with a
single +5V supply and have -75dB off-isolation and
-85dB crosstalk from the output to each off channel.
The switching times are 18ns tONand 7ns tOFF. They
feature a -3dB 85MHz bandwidth and a guaranteed
0.25nA leakage current at +25°C.
A +1.8V to +5.5V operating range makes the MAX4638/
MAX4639 ideal for battery-powered, portable instru-
ments. All channels guarantee break-before-make
switching. These parts feature bidirectional operation
and can handle Rail-to-Rail®analog signals. All control
inputs are TTL/CMOS-logic compatible. Decoding is in
standard BCD format, and an enable input is provided to
simplify cascading of devices. These devices are avail-
able in small 16-pin TQFN, TSSOP, and SO packages, as
well as a 20-pin TQFN package.

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.
