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 RON

resistance, excellent RON flatness, and fast switching

speeds (tON = 8ns, tOFF = 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.
