Detailed Description
The ISL84516 and ISL84517 analog switches offer precise
switching capability from
1.5V
to
6V
supplies with low on-
resistance (13) and high speed operation (t
ON
= 40ns, t
OFF
=
30ns). The devices are especially well suited to portable
battery powered equipment thanks to the low operating supply
voltage (1.5V), low power consumption (350W), 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.
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 1k 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 R
ON
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 V-. The
low leakage current performance is unaffected by this
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
6). To prevent forward biasing these diodes, V+ and V- must
