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 (1µA 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.
