The LTC2862A is a low power, 20Mbps or 250kbps RS485/RS422 transceiver operating on 3V to 5.5V supplies with ±60V overvoltage fault protection on the interface pins during all modes of operation, including power-down. Improvements were made to the LTC2862 for greater robustness and signal integrity: ±40kV HBM and Level 4 IEC ESD protection on the interface pins; increased resistance to electrical overstress; increased receiver noise immunity; additional receiver noise filtering on the LTC2862A-2; and an improved failsafe function optimized for high speed in the LTC2862A-1 and noise rejection in the LTC2862A-2. Low EMI slew rate limited data transmission is available in the 250kbps LTC2862A-2 option, while the LTC2862A-1 operates to 20Mbps.

Extended ±25V input common mode range and full failsafe operation improve data communication reliability in electrically noisy environments and in the presence of large ground loop voltages.

Product Detail

The EVAL-RS485HDEBZ allows quick and easy evaluation of half-duplex RS-485 transceivers with standard 8-lead SOIC footprints. The evaluation board allows interfacing via screw terminal block to digital I/O for driver input (DI), receiver output (RO), driver enable (DE) and receiver output (RO). Bus signals A and B (half-duplex bus) can be connected to a bus screw terminal block. One or two termination resistors can be connected to A and B via jumper settings, in order to evaluation the half-duplex RS-485 driver and receiver. Footprints are provided for pull-up and pull-down (biasing resistors) on the bus.

Devices for evaluation on the board must be ordered separately.
