SP3487 - +3.3V Low Power Quad RS-485/RS-422 Line Drivers

General Description

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.

Key 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.
