Ultra Low ON-Resistance, Low Voltage,
Single Supply, SPST Analog Switches
The Intersil ISL84715 and ISL84716 devices are low
ON-resistance, low voltage, bidirectional, single pole/single
throw (SPST) analog switches designed to operate from a
single +1.65V to +3.6V supply. Targeted applications include
battery powered equipment that benefit from low RON
resistance, excellent RON flatness, and fast switching
speeds (tON = 9ns, tOFF = 5ns). 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 family of parts may be used to
switch in additional functionality while reducing ASIC design
risk. The ISL8471X are offered in a 5 lead SC70 package,
alleviating board space limitations.
The ISL84715 has one normally open (NO) switch and
ISL84716 has one normally closed (NC) switch.

Detailed Description
The ISL84715 and ISL84716 are bidirectional, single
pole/single throw (SPST) analog switches. They offer
precise switching capability from a single 1.65V to 3.6V
supply with ultra low on-resistance and high speed
operation. With a single supply of 3V the typical on-
resistance is only 0.26, with a typical turn-on and turn-off
time of: tON = 9ns, tOFF = 5ns. The devices are especially
well suited for portable battery powered equipment due to its
low operating supply voltage (1.65V), low power
consumption (1.05µW), low leakage currents (35nA max), and
the tiny SC70 packaging.
The ISL84715 is a normally open (NO) SPST analog switch.
The ISL84716 is a normally closed (NC) SPST analog
switch.
Supply Sequencing And Overvoltage Protection
With any CMOS device, proper power supply sequencing is
required to protect the device from excessive input currents
which might permanently damage the IC. All I/O pins contain
ESD protection diodes from the pin to V+ and to GND (see
Figure 6). To prevent forward biasing these diodes, V+ must
be applied before any input signals, and the input signal
voltages must remain between V+ and GND. If these
conditions cannot be guaranteed, then one of the following
two protection methods should be employed.
Logic inputs can easily be protected by adding a 1k
resistor in series with the input (see Figure 6). The resistor
limits the input current below the threshold that produces
permanent damage, and the sub-microamp input current
produces an insignificant voltage drop during normal
operation.
This method is not acceptable for the signal path inputs.
Adding a series resistor to the switch input defeats the
purpose of using a low RON switch, so two small signal
diodes can be added in series with the supply pins to provide
overvoltage protection for all pins (see Figure 6). These
additional diodes limit the analog signal from 1V below V+ to
1V above GND. The low leakage current performance is
unaffected by this approach, but the switch signal range is
reduced and the resistance may increase, especially at low
supply voltages.

Power-Supply Considerations
The ISL8471X construction is typical of most single supply
CMOS analog switches in that they have two supply pins: V+
and GND. V+ and GND drive the internal CMOS switches
and set their analog voltage limits. Unlike switches with a 4V
maximum supply voltage, the ISL84714 4.8V maximum
