±15kV ESD protected, 16Mbps, Fail-Safe RS-485 transceiver BL1590

◉ BL1590 is a 3~5.5V wide power supply, half-duplex RS-485 transceiver, which contains one driver and one receiver inside the chip. It can achieve error-free data transmission up to 16Mbps. BL1590 has a built-in failure protection circuit to ensure that the output of the receiver is in a logic high state when the receiver input is open or shorted.

◉ BL1590 has excellent driving capability. The driver can provide a 3.4V differential output voltage under 5V power supply and 54Ω load conditions. BL1590 supports hot plugging. The driver and receiver are in the off state during power-on to avoid conflicts on the bus during plugging and unplugging.

◉ BL1590 has a 1 unit load receiver input impedance, allowing up to 32 transceivers to be connected to the bus. The I/O pin ESD protection capability reaches ±15KV IEC 61000-4-2, contact discharge.
