SP495 General Description

The SP495 is a quad differential line driver/receiver meeting both RS-485 and RS-422 standards at data rates beyond 10Mbps. The SP495 features three half-duplex transceivers suitable for data bus connections and a fourth full-duplex transceiver with independent driver, receiver enables. Ideal for use as a control bus transceiver. A complete SCSI initiator or target interface can be implemented using five SP495s. Propagation Delay Skew is tightly specified to aid in parallel interface designs. The SP495 is available in a 20-pin plastic SOIC package for operation over the commercial and industrial temperature ranges. For PLCC availability, please consult factory.
