ISL43110, ISL43111
Low-Voltage, Single Supply, SPST, High
Performance Analog Switches
The Intersil ISL4311X 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 (1
A Max over the temperature and
voltage ranges) and low leakage currents (1nA) make these
switches ideal for battery powered applications.
Low RON 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 ISL4311X 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 ISL43112/13 data
sheet.
