Detailed Description
The ISL54063 and ISL54064 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
Ω), high speed operation (t
ON = 55ns,
tOFF = 18ns) and negative signal swing capability. The
device is especially well suited for portable battery powered
equipment due to its low operating supply voltage (1.8V), low
power consumption (20nA), and a tiny 1.8mmx1.4mm
TQFN
package or a 3mmx3mm 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 ISL54063 is a normally open (NO) SPST analog switch.
The ISL54064 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. The ISL54063 and
ISL54064 contains ESD protection diodes on each pin of the
IC (see Figure 8). 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
must be implemented to prohibit the current and voltage at
the logic pin and signal pins from exceeding the maximum
ratings of the switch. The following two methods can be used
to 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
Ω resistor in
series with the logic input (see Figure 8). The resistor limits
the input current below the threshold that produces
permanent damage.
