SP3488 - Sipex

SP3488 +3.3V Low Power Quad RS-485/RS-422 Line Receivers

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 per.

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.
