DESCRIPTION
The ST1480A is ±15kV ESD protected, 3.3V low
power transceiver for RS-485 and RS-422
DIP
SOP
communications. The device contains one driver
and one receiver in half duplex configuration. The
ST1480A 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 ST1480A 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.
