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 lowvoltage switches an ideal solution for space constrained
products.

Detailed Description
Power-Supply Considerations
The ISL84514 and ISL84515 analog switches offer precise
switching capability from a single 2.4V to 12V supply with
low on-resistance, and high-speed operation. The devices
are especially well suited to portable battery powered
equipment thanks to the low operating supply voltage (2.4V),
low power consumption (5µW), low leakage currents (2nA
max), and the tiny SOT-23 packaging. High frequency
applications also benefit from the wide bandwidth, and the
very high Off Isolation.
The ISL8451X construction is typical of most CMOS analog
switches, except that there are only two supply pins: V+ and
GND. Unlike switches with a 13V maximum supply voltage,
the ISL8451X 15V maximum supply voltage provides plenty
of room for the 10% tolerance of 12V supplies, as well as
margin for overshoot and noise spikes.
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 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 1kΩ
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.
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 resistance may
increase, especially at low supply voltages.
The minimum recommended supply voltage is 2.4V. It is
important to note that the input signal range, switching times,
and on-resistance degrade at lower supply voltages. Refer to
the electrical specification tables and Typical Performance
Curves for details.
V+ and GND power the internal CMOS switches and set
their analog voltage limits. These supplies also power the
internal logic and level shifters. The level shifters convert the
input logic levels to switched V+ and GND signals to drive
the analog switch gate terminals.
This family of switches cannot be operated with bipolar
supplies, because the input switching point becomes
negative in this configuration. For a ±5V single SPST switch,
see the ISL84516, ISL84517 data sheet.
Logic-Level Thresholds
This switch family is TTL compatible (0.8V and 2.4V) over a
supply range of 3V to 11V, and the full temperature range
(see Figure 10). At 12V the low temperature VIH level is
about 2.5V. This is still below the TTL guaranteed high
output minimum level of 2.8V, but noise margin is reduced.
For best results with a 12V supply, use a logic family that
provides a VOH greater than 3V.
The digital input stages draw supply current whenever the
digital input voltage is not at one of the supply rails. Driving
the digital input signals from GND to V+ with a fast transition
time minimizes power dissipation.

In 50Ω systems, signal response is reasonably flat to
20MHz, with a -3dB bandwidth exceeding 200MHz (see
Figure 13). Figure 13 also illustrates that the frequency
response is very consistent over a wide V+ range, and for
varying analog signal levels.
An OFF switch acts like a capacitor and passes higher
frequencies with less attenuation, resulting in signal
feedthrough from a switch’s input to its output. Off Isolation is
the resistance to this feedthrough. Figure 14 details the high
Off Isolation provided by this family. At 10MHz, off isolation is
about 50dB in 50Ω systems, decreasing approximately 20dB
per decade as frequency increases. Higher load impedances
decrease Off Isolation due to the voltage divider action of the
switch OFF impedance and the load impedance.

Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin and both V+ and GND.
One of these diodes conducts if any analog signal exceeds
V+ or GND.
Virtually all the analog leakage current comes from the ESD
diodes to V+ or GND. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by either
V+ or GND and the analog signal. This means their leakages
will vary as the signal varies. The difference in the two diode
leakages to the V+ and GND pins constitutes the analogsignal-path leakage current. All analog leakage current flows
between each pin and one of the supply terminals, not to the
other switch terminal. This is why both sides of a given
switch can show leakage currents of the same or opposite
polarity. There is no connection between the analog-signal
paths and V+ or GND.
