Test Circuits and Waveforms
Detailed Description
The ISL5120–ISL5123 bidirectional, dual analog switches
offer precise switching capability from a single 2.7V to 12V
supply with low on-resistance (19Ω) and high speed
operation (t
especially well suited to portable battery powered equipment
thanks to the low operating supply voltage (2.7V), low power
consumption (5µW), low leakage currents (100pA max), and
the tiny SOT-23 packaging. High frequency applications also
benefit from the wide bandwidth, and the very high off
isolation and crosstalk rejection.

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 GND (See
Figure 8). 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 8). The resistor
limits the input current below the threshold that produces
permanent damage, and the sub-microamp input current
