DATASHEET
ISL43110, ISL43111
Low-Voltage, Single Supply, SPST, High Performance Analog Switches
The Intersil ISL43110 and ISL43111 are precision, high
performance analog switches that are fully specified for 3.3V,
5V, and 12V operation, and feature improved leakage, ICC and
switching time specifications.
Designed to operate from a single +2.4V to +12V supply, the low
supply current (1µA Max over-temperature and voltage ranges)
and low leakage currents (1nA) make these switches ideal for
battery powered applications.
Low r
ON
and fast switching speeds over a wide operating supply
range increase these devices usefulness in industrial
equipment, portable instruments, and as input signal
multiplexers for new generation, low supply voltage data
converters. Some of the smallest packages are available
alleviating board space limitations, and making Intersil’s newest
line of low-voltage switches an ideal solution.
The ISL43110 and ISL43111 are single-pole/single-throw
(SPST) switches, with the ISL43110 being normally open (NO),
and the ISL43111 being normally closed (NC).
Table 1
summarizes the performance of this family. For similar
performance ±5V supply versions, see the
ISL43112
and
ISL43113 data sheets.

NOTES:
1. Please refer to
TB347
for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
