ISL54060, ISL54061
Negative Signal Swing, Sub-ohm, Dual
SPST Single Supply Switch
The Intersil ISL54060 and ISL54061 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 (8nA)
and fast switching speeds (t
ON
=55ns, t
OFF
= 18ns). The
digital inputs are 1.8V logic-compatible up to a +3V supply.
The ISL54060, ISL54061 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 3x3mm TDFN
package.
The ISL54060 is a committed dual single-pole/single-throw
(SPST) that consist of two normally open (NO) switches with
independent logic control. The ISL54061 is a committed dual
single-pole/single-throw (SPST) that consist of two normally
closed (NC) switches with independent logic control.
