Test Circuits and Waveforms
Detailed Description
The ISL84051, ISL84052, ISL84053 analog switches offer
precise switching capability from a bipolar
single 2V to 12V supply with low on-resistance (60Ω) and
high speed operation (t
are especially well suited to portable battery powered
equipment thanks to the low operating supply voltage (2V),
low power consumption (3μW), low leakage currents (5nA
max). 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 to V- (see
Figure 8). To prevent forward biasing these diodes, V+ and
V- must be applied before any input signals, and input signal
voltages must remain between V+ and V-. 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
produces an insignificant voltage drop during normal
operation.
This method is not applicable for the signal path inputs.
Adding a series resistor to the switch input defeats the
