The MAX4617/MAX4618/MAX4619 construction is typi-
cal of most CMOS analog switches. They have two sup-
ply pins: V
the internal CMOS switches and set the limits of the ana-
log voltage on any switch. Reverse ESD-protection
diodes are internally connected between each analog-
signal pin and both V
exceeds V
During normal operation, these and other reverse-
biased ESD diodes leak, forming the only current drawn
from V
High-Speed, Low-Voltage, CMOS Analog
Multiplexers/Switches
Note: Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well

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. Each is biased by either
V
leakages will vary as the signal varies. The difference in
the two diode leakages to the V
stitutes the analog-signal-path leakage current. All ana-
log leakage current flows between each pin and one of
the supply terminals, not to the other switch terminal.
This is why both sides of a given switch can show leak-
age currents of either the same or opposite polarity.
