OA1 OB1 OA2 OB2 V
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
SP495
s. 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.
