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 (tON = 52ns,

tOFF = 40ns). A 5Ω maximum rON 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.
