MAX4638EUE

Product Summary

The MAX4638EUE is single 8:1 CMOS analog multiplexers(muxes). Each mux operates from a single +1.8V to +5V supply. These devices feature 3.5Ω on-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 +25°C. A +1.8V to +5.5V operating range makes the MAX4638EUE 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 QFN, TSSOP and SOIC packages, as well as a 20-pin QFN package.
