Huaguan Semiconductor Introduced RS-485 Interface IC HG3085E, Achieving Error-Free Data Transmission up to 500Kbps
The HG3085E for RS-485/RS-422 communication is a high-speed transceiver for half-duplex communication, which includes a driver and a receiver. With a fail-safe circuit, when the receiver input is open or short-circuited, it ensures that the receiver input logic is high. If all transmitters connected to the terminal match bus are disabled (high impedance), the receiver will output a logic high level. HG3085E has a low slew rate driver, which can reduce EMI and reflections caused by improper terminal matching cables, and achieve error-free data transmission up to 500Kbps; in addition, the receiver of HG3085E has 1/8 unit load input impedance, More than 256 transceivers can be connected to the bus.
