The Intersil ISL43143–ISL43145 devices are CMOS,

precision, quad SPST 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 (<1?W), low

leakage currents (5nA max), and fast switching speeds

(tON = 52ns, tOFF = 40ns). A 5? maximum RON flatness

ensures signal fidelity, while channel-to-channel mismatch is

guaranteed to be less than 2?.

The ISL43143/ISL43144/ISL43145 are quad single-pole/

single-throw (SPST) devices. The ISL43143 has four normally

closed (NC) switches; the ISL43144 has four normally open

(NO) switches; the ISL43145 has two NO and two NC

switches and can be used as a dual SPDT, or a dual 2:1

multiplexer.
