HX65LBC184-S

The HX65LBC184-S is an RS485/RS-422 transceiver circuit equipped with a 3.3V/5V voltage supply, half-duplex communication, and ±15kV ESD protection. This circuit encompasses a driver and a receiver. The HX65LBC184-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 15Mbps. The receiver input impedance of the HX65LBC184-S chip is 1/8 unit load, enabling the attachment of up to 256 transceivers for half-duplex communication on the bus. All driver outputs provide ±15kV human mode ESD protection. The chip is packaged in SOP8 and is capable of operating within a temperature range from -40℃ to +125℃
