MAX4643ETA+T Overview
Presented in 8-WDFN Exposed Pad, this electrical component is convenient for overseas shipping. A high level of reliability can be achieved through the use of an advanced packaging method Tape & Reel (TR). Mounted in Surface Mount is this multiplexer. Multiplexers and demultiplexers have a number of circuits 1:1. Temperatures around -40°C~85°C TA are extended for operation. Unlike digital switches, these are based on SPST - NO/NC switching circuits. There are 2 circuits in this multiplexer. MAX4643 can be used to search for analog multiplexer variants. The internal resistance of this digital multiplexer is 4Ohm. The datasheets for the 8 pins explain the functions. normally, users should not supply switches with voltages higher than 5.5V. Analog switch ics with Single supply type are cost-effective. 1.8V is the lowest voltage that should be fed to the electronic electronic part. This multiplexer would work with 1nA current. A voltage of 1.8V~5.5V is required to drain this analog switch from a single voltage supply.
