DESCRIPTION

The IC is an 8 channel analog multiplexer with a buffer amplifier. The input signals IN0 to IN7 are fed to the multiplexer consisting of analog transmission gates which are controlled by the digital inputs SEL0-2. The multiplexer is designed for low crosstalk in case of current injection into the input protection diodes.

VS is used as the positive supply voltage for the buffer and has to be at least 2.5V higher than the maximum analog voltage to avoid clipping or slew rate reduction of the output signal.
