Standard ICs
Single analog switch
BU4S66
The BU4S66 is an ultra-compact IC with one circuit of the bi-directional analog switch BU4066B built into an SMP
package. Setting the enable input (CONT) to the "H" level sets the impedance between the switch input and the out-
put pins low (ON state) and setting CONT to the "L" level sets the impedance high (OFF state).
