The SP3486 and the SP3487 are +3.3V low power quad drivers that meet the specifications of the RS-485 and RS-422 serial protocols. These devices are pin-to-pin compatible with Sipex's SP486 and SP487 devices as well as popular industry standards. The SP3486 and Sp3487 feature Sipex's BiCMOS process allowing low power operation without sacrificing performance. The SP3486 and SP3487 meet the electrical specifications of RS-485 and RS-422 serial protocols up to 10Mbps under load. The SP3486 features a common driver enable control. The SP3487 provides independent driver enable controls for each pair of drivers. Both devices feature tri-state outputs and a -7V to +12V common-mode input voltage range.
