FAIL-SAFE, 115KBPS, RS-485 /
RS-422 TRANSCEIVERS WITH
±12KV ESD-PROTECTED
CMOS IC
 DESCRIPTION
The UTC UTRS3082 is a half-duplex transceiver designed for
RS-485 data bus network, which contains one transmitter and one
receiver. The UTC UTRS3082 features a fail-safe receiver, which
guarantees the receiver to output high when the receiver inputs are
open, short or idle.
The UTC UTRS3082 also features a hot-swap glitch free protection
circuits which guarantee outputs of both the transmitter and the
receiver in a high impedance state during the power up period. So that
the large short current from power to ground will be disable by glitch
free function, which will save the power and enhance the efficiency of
the power up.
The UTC UTRS3082 is optimized for signal rates up to 115Kbps
with differential voltage of 2.3V. The UTC UTRS3082 also has the
thermal shutdown function when the temperature is over 150℃ and
the protection of the current limitation in the transmitter to protect the
itself from the damage by the system-fault conditions during normal
operation.
 FEATURES
* Meet the requirements of the EIA/TIA-485 standards.
* 5.0V single power supply.
* 1µA low-current shutdown mode.
* HBM ±12kV ESD protection.
