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 3.5on-resistance (RON) when powered with a single +5V supply and have -75dB of 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 +25C. 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 TSSOP and SOIC packages.
