ISL84714
Ultra Low ON-Resistance, Low Voltage,
Single Supply, SPDT Analog Switch
The Intersil ISL84714 device is a low ON-resistance, low
voltage, bidirectional, single pole/double throw (SPDT)
analog switch designed to operate from a single +1.65V to
+3.6V supply. Targeted applications include battery powered
equipment that benefit from low on-resistance and fast
switching speeds (t
ON
= 7.5ns, t
OFF
= 2.9ns). The digital logic
input is 1.8V CMOS compatible when using a single +3V
supply.
Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This part may be used to "mux-in"
additional functionality while reducing ASIC design risk. The
ISL84714 is offered in the 6 lead SC70 package, alleviating
board space limitations.
The ISL84714 is a committed SPDT that consist of one
normally (NO) and one normally (NC) switch. This
configuration can also be used as a 2-to-1 multiplexer.

5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
6. Parts are 100% tested at +25C. Limits across the full temperature range are guaranteed by design and correlation.
7. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
