UNISONIC TECHNOLOGIES CO., LTD UTRS3082 Preliminary FAIL-SAFE, 115KBPS, RS-485 / RS-422 TRANSCEIVERS WITH ±12KV ESD-PROTECTED  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.
