MaxLinear MxL83121
The MxL83121 and MxL83122 (MxL8312x family) of half-duplex RS-485 transceivers support up to 500kbps communication in harsh industrial environments. The bus pins tolerate high levels of IEC electrical fast transients (EFT), IEC electrostatic discharge (ESD), and provide an extended common mode range. The combination of integrated EFT and ESD protection, wide common mode, and low slew rate provide a high degree of protection, immunity to noise, and ultra-low EMI.| Part No. | MxL83121 |

GENERAL DESCRIPTION
Two product options with slew controlled 250kbps and 500kbps speeds are specifically designed to excel at long-distance communication. High receiver input impedance allows 256 transceivers to share a common data bus while maintaining signal margin and without excessive loading or use of expensive repeaters. Enhanced failsafe circuitry ensures receivers provide the expected output when the bus is shorted or left open under both terminated and unterminated conditions. Drivers include built-in short-circuit protection and a thermal-overload shutdown to protect against excessive power dissipation from bus contention.APPLICATIONS
