HX13082-S

The HX13082-S is a high-speed RS485/RS-422 transceiver circuit that supports +5V power supply with half-duplex functionality. The interior contains one driver and one receiver, which can achieve a transfer rate of up to 10Mbps. The circuit has ±15kV ESD protection function, which can effectively prevent the damage of electrostatic discharge to the chip. Both the driver and receiver have enable pins (DE and RE) that drive and receive outputs in a high resistance state when the enable pins are off. In addition, the HX13082-S has a fail-safe circuit that ensures that the output remains correct when the receiver input is open or short-circuited. The input impedance of the receiver is 1/8 unit load, allowing up to 256 transceivers to be attached to the same bus.
