Description
The BL3085A is a low-power transceiver for RS-485 communication, with one driver and one receiver in each device . The chip contains a fail-safe circuit to ensure that the output of the receiver is in a logic high state when the input of the receiver is open or short-circuited . The BL3085A features a slew-rate-limited driver that reduces EMI and reduces reflections caused by improperly terminated cables, enabling error-free data transmission up to 250kbps . The BL3085A has a high receive input impedance, making it possible to support up to 256 transceivers on the bus. The transceiver end of BL3085A has +/-10kV anti-static capability.
