ISL8394
Low-Voltage, Single and Dual Supply,
Quad SPDT, Analog Switches
The Intersil ISL8394 device is a precision, quad SPDT analog
switches designed to operate from a single +2V to +12V
supply or from a
2V to
6V supply. Targeted applications
include battery powered equipment that benefit from the
devices' low power consumption (5
W), low leakage currents
(2.5nA max), and fast switching speeds (t
ON
= 50ns,
t
OFF
= 30ns). A 4
maximum R
ON
flatness ensures signal
fidelity, while channel to channel mismatch is guaranteed to
be less than 2
.
The ISL8394 is a quad single-pole/double-throw (SPDT)
device and can be used as a quad SPDT, a quad 2:1
multiplexer, a single 4:1 multiplexer, or a dual 2-channel
differential multiplexer.
Table 1 summarizes the performance of this family. For higher
performance, pin compatible versions, see the ISL43240 data
sheet.

4. V
IN
= Input voltage to perform proper function.
5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
6. Leakage parameter is 100% tested at high temp, and guaranteed by correlation at 25
o
C.
7. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range. Flatness
specifications are guaranteed only with specified voltages.
8. Between any two switches.
