DATASHEET
ISL54060, ISL54061
Negative Signal Swing, Sub-ohm, Dual SPST Single Supply Switch
The Intersil ISL54060 and ISL54061 devices are a low
ON-resistance, low voltage, bi-directional, dual
single-pole/single-throw (SPST) analog switch. It is designed
to operate from a single +1.8V to +6.5V supply and pass
signals that swing down to 6.5V below the positive supply rail.
Targeted applications include battery powered equipment that
benefit from low rON (0.56low power consumption (8nA)
and fast switching speeds (tON = 55ns, tOFF = 18ns). The
digital inputs are 1.8V logic-compatible up to a +3V supply.
The ISL54060, ISL54061 are offered in a small form factor
package, alleviating board space limitations. It is available in a
tiny 10 Ld 1.8 x 1.4mm µTQFN or 10 Ld 3x3mm TDFN
package.
The ISL54060 is a committed dual single-pole/single-throw
(SPST) that consist of two normally open (NO) switches with
independent logic control. The ISL54061 is a committed dual
single-pole/single-throw (SPST) that consist of two normally
closed (NC) switches with independent logic control.

AUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
5. Signals on NC, NO, IN, or COM exceeding V+ or GND by the specified amount are clamped by internal diodes. Limit forward diode current to
maximum current ratings.
6. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379.
7. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
8. For JC, the “case temp” location is the center of the exposed metal pad on the package underside.

Detailed Description
The ISL54060 and ISL54061 are bidirectional, dual single
pole-single throw (SPST) analog switches that offers precise
switching from a single 1.8V to 6.5V supply with low
ON-resistance (0.83) and high speed operation (tON = 55ns,
tOFF = 18ns). The device is especially well suited for portable
battery powered equipment due to its low operating supply
voltage (1.8V), low power consumption (8nA), and a tiny
1.8x1.4mm µTQFN package or a 3x3mm TDFN package. The
low ON-resistance and rON flatness provide very low insertion
loss and signal distortion for applications that require signal
switching with minimal interference by the switch.
The ISL54060 is a normally open (NO) SPST analog switch.
The ISL54061 is a normally closed (NC) SPST analog switch.
input current below the threshold that produces permanent
damage.
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. Connecting external Schottky diodes
to the signal pins will shunt the fault current to the V+ supply
instead of through the internal ESD diodes thereby protecting
the switch. These Schottky diodes must be sized to handle the
expected fault current..

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. The ISL54060 and
ISL54061 contains ESD protection diodes on each pin of the
IC (see Figure 7). These diodes connect to either a +Ring or Ring for ESD protection. To prevent forward biasing the ESD
diodes to the +Ring, V+ must be applied before any input
signals, and the input signal voltages must remain between
recommended operating range.

If these conditions cannot be guaranteed, then precautions

provided additional protection to limit the current in the event
that the voltage at a logic pin or switch terminal goes above the
V+ rail.
Logic inputs can be protected by adding a 1k resistor in
series with the logic input (see Figure 7). The resistor limits the

Power-Supply Considerations
The ISL54060 and ISL54061 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 5.5V maximum supply voltage, the ISL54060
and ISL54061 have a 6.5V maximum supply voltage providing
plenty of head room for the 10% tolerance of 5V supplies due
to overshoot and noise spikes.
The minimum recommended supply voltage is 1.8V. It is
important to note that the input signal range, switching times,
and ON-resistance degrade at lower supply voltages. Refer to
the “Electrical Specifications” tables, beginning on page 4, and
“Typical Performance Curves”, beginning on page 11, for
details.
V+ and GND also power the internal logic and level shifters.
The level shifters convert the input logic levels to V+ and GND
signals levels to drive the analog switch gate terminals. A high
frequency decoupling capacitor placed as close to the V+ and
GND pin as possible is recommended for proper operation of
the switch. A value of 0.1µF is highly recommended.
Negative Signal Swing Capability
The ISL54060 and ISL54061 contains circuitry that allows the
analog switch signal to swing below ground. The device has an
analog signal range of 6.5V below V+ up to the V+ rail (see
Figure 13) while maintaining low rON performance. For
example, if V+ = 5V, then the analog input signal range is from
-1.5V to +5V. If V+ = 2.7V then the range is from -3.8V to
+2.7V.
An OFF switch acts like a capacitor across the open terminals
and AC couples higher frequencies, resulting in signal feedthrough from a switch’s input to its output. Off-Isolation is the
resistance to this feed-through. Crosstalk indicates the amount
of feed-through from one switch channel to another switch
channel. Figure 19 details the high Off-Isolation and Crosstalk
rejection provided by this part. At 100kHz, Off-Isolation is about
60dB in 50 systems, decreasing approximately 20dB per
decade as frequency increases. At 1MHz, Crosstalk is about 75dB in 50 systems, decreasing approximately 20dB per
decade as frequency increases.
Leakage Considerations
Reverse ESD protection diodes are internally connected between
each analog-signal pin, V+ and GND. One of these diodes
conducts if any analog signal exceeds the recommended analog
signal range.
Virtually all the analog switch leakage current comes from the
ESD diodes and reversed biased junctions in the switch cell.
Although the ESD diodes on a given signal pin are identical
and therefore fairly well balanced, they are reverse biased
differently. Each is biased to either the +Ring or -Ring and the
analog input signal. This means their leakages will vary as the
signal varies. The difference in the two diode leakages to the
+Ring or -Ring and the reverse biased junctions at the internal
switch cell constitutes the analog-signal-path leakage current.
Logic-Level Thresholds
This switch family is 1.8V CMOS compatible (0.45V VOLMAX
and 1.35V VOHMIN) over a supply range of 1.8V to 3.3V (see
Figure 15). At 3.3V the VIL level is 0.5V maximum. This is still
below the 1.8V CMOS guaranteed low output maximum level
of 0.45V, but noise margin is reduced. At 3.3V the VIH level is
1.4V minimum. While this is above the 1.8V CMOS guaranteed
high output minimum of 1.35V under most operating conditions
the switch will recognize this as a valid logic high.
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. The ISL54060, ISL54061 has
been designed to minimize the supply current whenever the
digital input voltage is not driven to the supply rails (0V to V+).
For example driving the device with 2.85V logic high while
operating with a 4.2V supply the device draws only 1µA of
current.
High-Frequency Performance
In 50 systems, the ISL54060, ISL54061 has an ON switch 3dB bandwidth of 60MHz (see Figure 18). The frequency
response is very consistent over a wide V+ range, and for
varying analog signal levels.
