The Intersil ISL84514 and ISL84515 devices are precision, analog switches designed to operate from a single +2. 4V to +12V supply. Targeted applications include battery powered equipment that benefit from the devices’ low power consumption (5µW), and low leakage currents (1nA). Low rON and fast switching speeds over a wide operating supply range make these switches ideal for use in industrial equipment, portable instruments, and as input signal multiplexers for new generation, low supply voltage data converters. Some of the smallest packages available alleviate board space limitations, and make Intersil’s newest line of low-voltage switches an ideal solution for space constrained products. The ISL8451x are single-pole/single-throw (SPST) switches, with the ISL84514 being normally open (NO), and the ISL84515 being normally closed (NC). Table 1 summarizes the performance of this family. For higher performance, pin compatible versions, see the ISL43110, ISL43111 datasheet. For ±5V supply versions, see the ISL84516, ISL84517 datasheet.
