ISL54063, 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 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.
