FN6130.0
Ultra Low ON-Resistance, +1.1V to +4.5V
Single Supply, SPST Analog Switches
The Intersil ISL43L110 and ISL43L111 devices are low
ON-resistance, low voltage, bidirectional, single pole/single
throw (SPST) analog switches designed to operate from a
single +1.1V to +4.5V supply. Targeted applications include
battery powered equipment that benefit from low R
ON
resistance, excellent R
ON
flatness, and fast switching
speeds (t
ON
= 8ns, t
OFF
= 5ns). The digital logic input is
1.8V CMOS compatible when using a single +3V supply.
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 ISL43L11X are offered in a 5 lead SC70 package,
alleviating board space limitations.
The ISL43L110 has one normally open (NO) switch and
ISL43L111 has one normally closed (NC) switch.
