FN6039.2
ISL8391, ISL8392, ISL8393
Low-Voltage, Single and Dual Supply,
Quad SPST, Analog Switches
The Intersil ISL8391–ISL8393 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 (<1µW), low
leakage currents (2.5nA max), and fast switching speeds
(t
ON
= 60ns, t
OFF
= 30ns). A 4Ω maximum R
ON
flatness
ensures signal fidelity, while channel-to-channel mismatch is
guaranteed to be less than 2Ω.
The ISL8391, ISL8392, and ISL8393 are quad
single-pole/single-throw (SPST) devices. The ISL8391 has
four normally closed (NC) switches; the ISL8392 has four
normally open (NO) switches; the ISL8393 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. For higher
performance, pin compatible versions, see the ISL43143-5
data sheet.
