DESCRIPTION
The ST3485E is ±15kV ESD protected, 3.3V low
power
transceiver
for
communications. The device contains one driver
RS-485
and
RS-422
and one receiver in half duplex configuration. The
ST3485E transmit and receive at guaranteed data
rate at least to 12Mbps.
All transmitter outputs and receiver inputs are
protected to ±15kV using Human Body Model.
Driver is short-circuit current limited and is
protected against excessive power dissipation by
thermal shutdown circuitry that place the driver
outputs into a high-impedance state.
The ST3485E input has a true fail-safe feature
that guarantees a logic high output if both inputs
are open circuit, shorted together or in presence of
the termination with no signal on the bus.
