The SP506 is pin-to-pin compatible to our SP505 multi-protocol transceiver but with faster throughput. The seven (7) drivers and seven (7) receivers can transmit and receive signals at 20Mbps. As with the SP505, the SP506 requires no additional external components for compliant operation for all of the eight (8) modes of operation. All necessary termination is integrated within the SP506 and is switchable when V.35 drivers, V.35 receivers, and V.11 receivers are used. The SP506 can operate as either a DTE or DCE. Additional features with the SP506 include internal loopback that can be initiated in either singleended or differential modes. While in loopback mode, driver outputs are internally connected to receiver inputs creating an internal signal path convenient for diagnostic testing. This eliminates the need for an external loopback plug. The SP506 also includes a latch enable pin with the driver and receiver address decoder. Tri-state ability for the driver and receiver outputs is controlled by supplying a 4-bit word into the address decoder. Seven (7) drivers and one (1) receiver in the SP506 include separate enable pins for added convenience.

Large high density plastic packages are moisture sensitive and should be stored in Dry Vapor Barrier Bags. Prior to usage, the parts should remain bagged and stored below 40°C and 60%RH. If the parts are removed from the bag, they should be used within 48 hours or stored in an environment at or below 20%RH. If the above conditions cannot be followed, the parts should be baked for four hours at 125°C in order remove moisture prior to soldering. Exar ships the 80-pin QFP in Dry Vapor Barrier Bags with a humidity indicator card and desiccant pack. The humidity indicator should be below 30%RH.
