ISL43140, ISL43141, ISL43142
Low-Voltage, Single and Dual Supply,
High Performance, Quad SPST, Analog
Switches
The Intersil ISL43140ISL43142 devices are CMOS,
precision, quad 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 (1nA max), and fast switching speeds
(t
ON
= 30ns, t
OFF
= 18ns). A 12
maximum R
ON
flatness
ensures signal fidelity, while channel-to-channel mismatch is
guaranteed to be less than 2.5
. The 3mm x 3mm Quad No-
Lead Flatpack (QFN) package alleviates board space
limitations, making this newest line of low-voltage switches an
ideal solution.
The ISL43140/ISL43141/ISL43142 are quad single-pole/
single-throw (SPST) devices. The ISL43140 has four normally
closed (NC) switches; the ISL43141 has four normally open
(NO) switches; the ISL43142 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.
