ISL43143, ISL43144, ISL43145
Low-Voltage, Single and Dual Supply,
Quad SPST, High Performance Analog
Switches
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
µW), 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 2
Ω.
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.
Table 1 summarizes the performance of this family.
