Description
BL1585B is a 5V power supply, half-duplex RS-485 transceiver, the chip contains a driver and a receiver. The BL1585B uses a slew-rate-limited driver, which can significantly reduce EMI and reflections caused by improperly terminated cables, and realize
Now up to 500kbps error-free data transmission. BL1585B has a built-in 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.
BL1585B receiver is 1/8 unit load, allowing up to 256 transceivers to be connected to the bus to realize half-duplex communication. BL1585B I/O pins have 15kV IEC 61000-4-2 contact discharge protection capability.
