Detailed Description
The ISL84714 is a bi-directional, single pole/double throw
(SPDT) analog switch that offers precise switching capability
from a single 1.65V to 3.6V supply with low ON-resistance
(0.44
Ω) and high speed operation (t
ON = 7.5ns, tOFF = 2.9ns).
The device is especially well suited for portable battery
powered equipment due to its low operating supply voltage
(1.65V), low power consumption (1.05W), low leakage
currents (20nA max), and the tiny SC70 packaging. The ultra
low ON-resistance and rON flatness provide very low insertion
loss and distortion to application that require signal
reproduction.
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 GND (See
Figure 8). To prevent forward biasing these diodes, V+ must
be applied before any input signals, and the 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.
