ROHM BU4S66

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 output pins low (ON state) and setting CONT to the "L" level sets the impedance high (OFF state).
•1)Features
Low current dissipation.
3) Wide range of operating power supply voltage.
4) Direct drive of 2 L-TTL inputs and 1 LS-TTL input.
2) Super-mini mold package designed for surface
mounting.
