+1.8V to +6.5V, Sub-ohm, Dual SPST
Analog Switch with Negative Signal
Capability and Click and Pop Elimination
Features
• Pb-free (RoHS Compliant)
• Negative Signal Capability
• Audio Click and Pop Elimination Circuitry
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
to operate from a single +1.8V to +6.5V supply and pass
signals that swing up to 6.5V below the positive supply rail.
Targeted applications include battery powered equipment that

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.
