Low-Voltage, Single Supply, SPST, High
Performance Analog Switches
Features
• Fully Specified at 3.3V, 5V, and 12V Supplies
• Available in SOT-23 Packaging
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 (1µA Max over the temperature and
voltage ranges) and low leakage currents (1nA) make these
switches ideal for battery powered applications.

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.
