ISL43L120, ISL43L121, ISL43L122
Ultra Low ON-Resistance, Single Supply,
Dual SPST Analog Switches
The Intersil ISL43L120, ISL43L121, ISL43L122 devices are
low ON-resistance, low voltage, bidirectional, precision, dual
single-pole/single-throw (SPST) analog switches designed
to operate from a single +1.65V to +3.6V supply. Targeted
applications include battery powered equipment that benefit
from low R
ON
(0.16), low power consumption (0.12W)
and fast switching speeds (t
ON
= 13ns, t
OFF
= 13ns).
Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This family of parts may be used to
switch in additional functionality while reducing ASIC design
risk. The ISL43L12X are offered in an 8 Ld MSOP package,
alleviating board space limitations.
The ISL43L120, ISL43L121, ISL43L122 are dual single-
pole/single-throw (SPST) devices. The ISL43L120 has two
normally open (NO) switches; the ISL43L121 has two
normally closed (NC) switches; the ISL43L122 has one
normally open (NO) and one normally closed (NC) switch
and can be used as an SPDT.
Table 1 summarizes the performance of this family.
