__________Applications Information
Power-Supply Considerations
Overview
The MAX4581/MAX4582/MAX4583 construction is typi-
cal of most CMOS analog switches. They have three
supply pins: V
CC
, V
EE
, and GND. V
CC
and V
EE
are used
to drive the internal CMOS switches and set the limits of
the analog voltage on any switch. Reverse ESD-
protection diodes are internally connected between
each analog-signal pin and both V
CC
and V
EE
. If any
analog signal exceeds V
CC
or V
EE
, one of these diodes
Pin Description
Note: Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well
in both directions.

will conduct. During normal operation, these and other
reverse-biased ESD diodes leak, forming the only cur-
rent drawn from V
CC
or V
EE
.
Virtually all the analog leakage current comes from the
ESD diodes. Although the ESD diodes on a given sig-
nal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by
either V
CC
or V
EE
and the analog signal. This means
their leakages will vary as the signal varies. The
differ-
ence
in the two diode leakages to the V
CC
and V
EE
pins constitutes the analog-signal-path leakage current.
All analog leakage current flows between each pin and
one of the supply terminals, not to the other switch ter-
minal. This is why both sides of a given switch can
show leakage currents of either the same or opposite
polarity.
There is no connection between the analog-signal
paths and GND.
V
CC
and GND power the internal logic and logic-level
translators, and set the input logic limits. The logic-level
translators convert the logic levels into switched V
CC
and V
EE
signals to drive the gates of the analog sig-
nals. This drive signal is the only connection between
the logic supplies and signals and the analog supplies.
V
CC
and V
EE
have ESD-protection diodes to GND.
The logic-level thresholds are TTL/CMOS compatible
when V
CC
is +5V. As V
CC
rises, the threshold increases
