FN6086.1
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 (tON = 7.5ns, tOFF = 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.

Detailed Description
The ISL84714 is a bidirectional, single pole/double throw
(SPDT) analog switch that offers precise switching capability
from a single 1.65V to 3.6V supply with low on-resistance
(0.44) and high speed operation (tON = 7.5ns, tOFF = 2.9ns).
The device is 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 (20nA max), and the tiny SC70 packaging. The ultra
low on-resistance and Ron flatness provide very low insertion
loss and distortion to application that require signal
reproduction.

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 8). 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.
