HX3483-S

The HX3483- S is an RS485/RS- 422 transceiver circuit equipped with a 3.3V/ 5V voltage supply, half- duplex communication, and ± 15 kV ESD protection. This circuit encompasses a driver and a receiver. The HX3483- S showcases enhanced swing rate limits, which assist in minimizing output electromagnetic interference (EMI) and alleviating reflections caused by mismatched terminal connections, facilitating error- free data transfer rates of up to 500Mbps. The receiver input impedance of the HX3483- S chip is 1/8 unit load, enabling the achievement of up to 256 transceivers for half- duplex communication on the bus. All driver outputs provide ± 15 kV human mode ESD protection. The chip is packaged in SOP8 and is capable of operating within a temperature range from - 40 °C to +125 °C
