General Description
The MAX3158 is a high CMRR RS-485/RS-422 data-com-
munications interface providing ±60V isolation in a
hybrid microcircuit. A single +5V supply on the logic side
powers both sides of the interface, with external 100V
capacitors transferring power from the logic side to the
isolated side. Each MAX3158 contains one transmitter
and one receiver and is guaranteed to operate at data
rates up to 250kbps. Drivers are short-circuit current lim-
ited and protected against excessive power dissipation
by thermal shutdown circuitry that places the driver out-
puts into a high-impedance state. The receiver input has
a fail-safe feature that guarantees a logic-high receiver
output if the inputs are open, shorted, or connected to a
terminated transmission line with all drivers disabled.
The MAX3158 typically draws 25mA of supply current
when unloaded or when fully loaded with the driver dis-
abled. Supply current drops to 25μA when the device is
placed in shutdown mode. The device is pin selectable
between half- and full-duplex mode and also features
an independently programmable receiver and transmit-
ter output phase through separate pins. The MAX3158
is a low-cost replacement for opto-isolated trans-
ceivers. For fully isolated RS-485/RS-422 transceivers,
refer to the MAX1480 family data sheet.
