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
R_ON 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.
