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 down to 6.5V below the positive supply rail.

Targeted applications include battery powered equipment that

benefit from low rON (0.56Ω), low power consumption (20nA)

and fast switching speeds (tON = 55ns, tOFF = 18ns). The

digital inputs are 1.8V logic-compatible up to a +3V supply.

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.
