Low-Voltage, Single and Dual Supply,

Triple SPDT Analog Switch

The Intersil ISL43231 device is a precision, bidirectional,

analog switches configured as a a triple single pole/double

throw (SPDT) switch, designed to operate from a single +2V

to +12V supply or from a

鹵

2V to

鹵

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鈩?with a

鹵

5V supply and 125鈩?with a

+3.3V supply. Each switch can handle rail to rail analog

signals. The off-leakage current is only 0.1nA at +25

o

C

or

2.5nA at +85

o

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

鹵

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.
