... Rev 2; 2/04 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 (R ) when powered with a ON single +5V supply and have -75dB off-isolation and -85dB crosstalk from the output to each off channel ...

... their maximum ratings. Limit forward-diode current to maximum current rating. 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. ELECTRICAL CHARACTERISTICS— ...

... The MAX4638 is an 8:1 mux that switches one of eight inputs (NO1–NO8 common output (COM) as determined by the 3-bit binary inputs A0, A1, and A2. The MAX4639 is a 4:1 dual mux that switches one of four differential inputs to a common differential out- put as determined by the 2-bit binary inputs A0 and A1. ...
