will conduct. During normal operation, these and other
reverse-biased ESD diodes leak, forming the only cur-
rent drawn from V
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
their leakages will vary as the signal varies. The differ-
ence in the two diode leakages to the V
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
