DESCRIPTION

The

SP3481

and the

SP3485

are a family of +3.3V low power half-duplex transceivers that

meet the specifications of the RS-485 and RS-422 serial protocols. These devices are pin-to-

pin compatible with the Sipex SP481, SP483, and SP485 devices as well as popular industry

standards. The

SP3481

and the

SP3485

feature Sipex's BiCMOS process, allowing low power

operation without sacrificing performance. The

SP3481

and

SP3485

meet the electrical

specifications of RS-485 and RS-422 serial protocols up to 10Mbps under load. The

SP3481

is equipped with a low power Shutdown mode.
