ISL84514, ISL84515

Low-Voltage, Single Supply, SPST, Analog Switches

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 data sheet. For ±5V supply versions, see the

ISL84516, ISL84517 data sheet.
