and amplitude are also determined by the resistance
between the remote ground and the ISOCOM pin. The
receiver input resistors will cause the isolated common
voltage to go to the mean voltage of the receiver inputs,
which will be a direct function of the remote ground
potential. The receiver input resistance and the capaci-
tors C1, C2, and C4 set up a time constant that limits
how fast the ISOCOM pin can follow variations in the
remote ground voltage. Connecting YR and ZR in half-
duplex operation, or AR and BR in full-duplex operation,
to ISOCOM results in a relatively low input impedance of
the MAX3158 receiver inputs (2k
). This allows for a
60Hz sine wave with a 60V maximum amplitude (see
Typical Operating Characteristics
). If YR, ZR, AR, and
BR are left open, the receiver input impedance is 12k
allowing up to 32 transceivers on the bus. To guarantee
the same low time constant under those conditions, use
a shielded cable with a 1k
resistor connected between
the shield and ISOCOM. Using a lower value for this
resistor is not recommended because this could trigger
a holding current in the internal ESD protection device if
the ±75V isolation limit is exceeded.
A single point hard-ground connection for the shield is
recommended.
Communication Between
Two MAX3158s
If two MAX3158 devices are used to communicate with
each other, one of the devices must have ISOCOM
connected to local ground. Failure to do so will result in
floating ISOCOM pins, with both devices trying to adapt
to the isolated ground of the other.
