ISL84521, ISL84522, ISL84523
Low-Voltage, Single and Dual Supply,
Quad SPST, Analog Switches
The Intersil ISL84521, ISL84523, ISL84523 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
= 45ns, t
OFF
= 15ns). A12
maximum R
ON
flatness
ensures signal fidelity, while channel-to-channel mismatch is
guaranteed to be less than 4
.
The ISL84521, ISL84522, ISL84523 are quad
single-pole/ single-throw (SPST) devices. The ISL84521 has
four normally closed (NC) switches; the ISL84522 has four
normally open (NO) switches; the ISL84523 has two NO and
two NC switches and can be used as a dual SPDT, or a dual
2:1 multiplexer.
Table summarizes the performance of this family. For higher
performance, pin compatible versions and 3mm x 3mm Quad
No-Lead Flatpack (QFN) package see the ISL43140,
ISL43142 data sheet.
