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 (tON = 40ns,
tOFF = 30ns). The devices are especially well suited to
portable battery powered equipment thanks to the low
operating supply voltage (
±1.5V), low power consumption
(350
W), 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.
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 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 RON 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
