DESCRIPTION
The
SP3493
and the
3494
devices are +3.3V, low power transceivers that meet the
specifications of the RS-485 and RS-422 serial protocols. The
SP3493
and the
3494
devices
are pin-to-pin compatible with the
Sipex SP3490
and the
SP3481
devices, respectively, as well
as other popular industry standards. The devices feature
Sipex's
BiCMOS process, allowing
low power operation without sacrificing performance. The partially slew-rate limited drivers
minimize EMI and reduce reflections caused by improperly terminated cables allowing
error-free data transmission. The
SP3493
is a full-duplex low power transceiver that will
deliver a data transmission rate up to 250kbps. The
SP3494
is a half-duplex partially slew-rate
limited transceiver that will deliver a data transmission rate up to 2.5Mbps. The
SP3494
is
equipped with a low-power shutdown mode and driver/receiver high-Z enable lines.
