ISL43231
Low-Voltage, Single and Dual Supply,
Triple SPDT Analog Switch
The Intersil ISL43231 device is a precision, bidirectional,
analog switch configured as a a triple single pole/double throw
(SPDT) switch, designed to operate from a single +2V to
+12V supply or from a
2V to 6V supply. The device has an
inhibit and inhibit bar pin to simultaneously open all signal
paths. The device also has a latch bar pin to lock in the last
switch address.
ON-resistance of 39 with a
5V supply and 125 with a
+3.3V supply. Each switch can handle rail-to-rail analog
signals. The off-leakage current is only 2.5nA at +85°C
.
All digital inputs have 0.8V to 2.4V logic thresholds, ensuring
TTL/CMOS logic compatibility when using a single +3.3V or
+5V supply or dual
5V supplies.
The ISL43231 is a committed triple SPDT, which is perfect for
use in 2-to-1 multiplexer applications. Table 1 summarizes the
performance of this part.
