MAX4638/MAX4639
3.5Ω, Single 8:1 and Dual 4:1,
Low-Voltage Analog Multiplexers
General Description
The 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 3.5Ω on-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 tON and 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.
