ISL54064: Negative Signal Swing, Sub-ohm, Dual SPST with Click and Pop Elimination Single Supply Switch

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.
