The UTC UTRS3088G is a half-duplex transceiver designed for RS-485 data bus network, which contains one transmitter and one receiver. The UTC UTRS3088G features a fail-safe receiver, which guarantees the receiver to output high when the receiver inputs are open, short or idle. The UTC UTRS3088G 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 UTRS3088G is optimized for signal rates up to 1.0Mbps with differential voltage of 2.3V. The UTC UTRS3088G 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.
