PIN DESCRIPTION
Description
Analog inputs/outputs
Multiplexer output/demultiplexer input
Open drain low impedance to analog ground when any channel is selected
Logic inputs to selected desired multiplexer(s) when using several multiplexers in a system
Binary address inputs to determine which channel is selected
Strobe input that latches A0, A1, A2, A3, CS, CS, EN
Positive supply voltage input
Analog signal ground and most negative potential
All ground pins should be connected externally to ensure dynamic performance
