DescripTion
Dual Isolated RS232
µModule Transceiver + Power
The LTM
®
2882 is a complete galvanically isolated dual
RS232 µModule
®
transceiver. No external components
are required. A single 3.3V or 5V supply powers both
sides of the interface through an integrated, isolated DC/
DC converter. A logic supply pin allows easy interfacing
with different logic levels from 1.62V to 5.5V, independent
of the main supply.
Coupled inductors and an isolation power transformer
provide 2500V
RMS
of isolation between the line transceiver
and the logic interface. This device is ideal for systems
with different grounds, allowing for large common mode
voltages. Uninterrupted communication is guaranteed for
common mode transients greater than 30kV/μs.
This part is compatible with the TIA/EIA-232-F standard.
Driver outputs are protected from overload and can be
shorted to ground or up to ±15V without damage. An
auxiliary isolated digital channel is available. This channel
allows configuration for half-duplex operation by control-
ling the DE pin.
Enhanced ESD protection allows this part to withstand up
to ±10kV (human body model) on the transceiver interface
pins to isolated supplies and across the isolation barrier
to logic supplies without latchup or damage.
