Low-Voltage, Single Supply, SPST, High Performance
Analog Switches
ISL43110, ISL43111
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.
