They are bidirectional switches, thus any analoginput may be used as an output and visa-versa. Also theMM74HC4066 switches contain linearization circuitrywhich lowers the “ON” resistance and increases switch lin-earity. The MM74HC4066 devices allow control of up to12V (peak) analog signals with digital control signals of thesame range. Each switch has its own control input whichdisables each switch when LOW. All analog inputs and out-puts and digital inputs are protected from electrostaticdamage by diodes to VCC and ground.FeaturesI Typical switch enable time: 15 nsI Wide analog input voltage range: 012VI Low “ON” resistance: 30 typ. (MM74HC4066)I Low quiescent current: 80 A maximum (74HC)I Matched switch characteristicsI Individual switch controls Ordering Code:Devices also available in Tape and Reel.
