Overview
The MAX4617/MAX4618/MAX4619 construction is typi-
cal of most CMOS analog switches. They have two sup-
ply pins: VCC and GND. VCC and GND are used to drive
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 VCC and GND. If any analog signal
exceeds VCC or GND, one of these diodes conducts.
During normal operation, these and other reverse-
biased ESD diodes leak, forming the only current drawn
from VCC 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. Each is biased by either
VCC or GND and the analog signal. This means their
leakages will vary as the signal varies. The
difference in
the two diode leakages to the VCC and GND pins con-
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.
VCC and GND power the internal logic and set the input
logic limits. Logic inputs have ESD-protection diodes to
ground.
Note: Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well
in both directions.
Digital Enable Input. Normally connect to GND. Can be driven
to logic high to set all switches off.
