The Intersil ISL54063 and ISL54064 devices are a low  
ON-resistance, low voltage, bi-directional, dual  
single-pole/single-throw (SPST) analog switch. It is designed  
Features  
• Pb-free (RoHS Compliant)  
to operate from a single +1.8V to +6.5V supply and pass  
signals that swing down to 6.5V below the positive supply rail.  
Targeted applications include battery powered equipment that  
• Negative Signal Swing (Max 6.5V below V+)  
• Audio Click and Pop Elimination Circuitry  
• ON-Resistance (r

benefit from low r  
and fast switching speeds (t

The ISL54063 and ISL54064 also features integrated circuitry  
to eliminate click and pop noise to an audio speaker. The  
ISL54063, ISL54064 are offered in a small form factor  
package, alleviating board space limitations. It is available in a  
tiny 10 Ld 1.8 x 1.4mm µTQFN or 10 Ld 3mmx3mm TDFN  
package.

The ISL54063 is a committed dual single-pole/single-throw  
(SPST) that consist of two normally open (NO) switches with  
independent logic control. The ISL54064 is a committed dual  
single-pole/single-throw (SPST) that consist of two normally  
closed (NC) switches with independent logic control.
