DESCRIPTION…
The SP3488 and the SP3489 are +3.3V low power quad line receivers that meet the
specifications of the RS-485 and RS-422 serial protocols. These devices are pin-to-pin
compatible with Sipex's SP488 and SP489 devices as well as popular industry standards.
The SP3488 and SP3489 feature Sipex's BiCMOS process allowing low power operation
without sacrificing performance. The SP3488 and SP3489 meet the electrical specifications
of RS-485 and RS-422 serial protocols up to 10Mbps under load. The SP3488 features a
common receiver enable control. The SP3489 provides independent receiver enable
controls for each pair of receivers. Both devices feature tri-state outputs and a -7V to +12V
common-mode input range. The receivers have a fail-safe feature which forces a logic "1"
output when receiver inputs are left floating.
