EVAL-RS485FDEBZ allow quick and easy evaluation of RS-485 EVAL-RS485FDEBZ transceivers with standard SOIC footprints. The evaluation board allows all of the input and output functions to be exercised without the need for external components. Screw terminal blocks provide convenient connections for power and ground, digital I/O, and RS-485 signals. The EVAL-RS485HDEBZ evaluation board has a footprint for a half-duplex RS-485 transceiver in an 8-lead SOIC package. The EVAL-RS485FD8EBZ evaluation board has a footprint for a full-duplex RS-485 transceiver in an 8-lead SOIC package. The EVAL-RS485FDEBZ evaluation board has a footprint for a full-duplex RS-485 transceiver in a 14-lead SOIC package. Figure 3.
