MAX4638, MAX4639 3.5�, Single 8:1 And Dual 4:1, Low-Voltage Analog Multiplexers

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 feature 3.5 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 +25C.
A +1.8V to +5.5V operating range makes the MAX4638 MAX4639 ideal for battery-powered, portable instruments. 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 available in small 16-pin thin QFN, TSSOP, and SO packages, as well as a 20-pin thin QFN package.
