The MAX4581L/MAX4582L/MAX4583L are low-voltage,
CMOS analog ICs that operate from a single supply of
+2V to +12V. The MAX4581L is configured as an 8-
channel multiplexer, the MAX4582L as two 4-channel
multiplexers, and the MAX4583L as three single-
pole/double-throw (SPDT) switches. These devices can
handle rail-to-rail analog signals with only 2nA of off-
leakage current at +25°C.
The MAX4581L/MAX4582L/MAX4583L are TTL/CMOS-
logic compatible with 0.8V to 2.0V logic thresholds for
all digital inputs when operating from a +12V supply.
The MAX4581L/MAX4582L/MAX4583Ls’ construction is
typical of most CMOS analog switches. The supply

switch. Reverse ESD protection diodes are internally
connected between each analog signal pin and both

During normal operation, these reverse-biased ESD
diodes leak, causing the only current drawn from V
or GND. Virtually all the analog leakage current comes
from the ESD diodes. Although the ESD diodes on a
given signal pin are identical, and therefore fairly well
balanced, they are reverse biased differently by either

leakage varies as the analog signal varies. The differ-
ence in the two diodes’ leakage to V
stitutes the analog signal-path leakage current.
Because there is no connection between the analog
signal paths and GND, all analog leakage current flows
between each pin and one of the supply terminals, not
to the other switch terminal. Because of this, both sides
of a given switch can show leakage currents of either
the same or opposite polarity.

Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
