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 r_ON (0.56Ω), low power consumption (20nA) and fast switching speeds (t_ON = 55ns, t_OFF = 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.
