DATASHEET
ISL43240
Low-Voltage, Single and Dual Supply, Quad SPDT, High Performance Analog
Switch
The Intersil ISL43240 device is a CMOS, precision, quad SPDT
analog switch 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 (5µW), low leakage currents
(5nA max), and fast switching speeds (t
ON
= 52ns,
t
OFF
= 40ns). A 5Ω maximum r
ON
flatness ensures signal
fidelity, while channel-to-channel mismatch is guaranteed to
be less than 2Ω.
The ISL43240 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.

9. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
10. Leakage parameter is 100% tested at high temp, and guaranteed by correlation at +25°C.
11. Flatness is defined as the delta between the maximum and minimum r
ON
values over the specified voltage range.
