DESCRIPTION

The

SP3490

and the

SP3491

are +3.3V low power full 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

SP490 and SP491 devices as well as popular industry standards.

The

SP3490

and the

SP3491

feature

Sipex's

BiCMOS process, allowing low power operation

without sacrificing performance. The

SP3490

and

SP3491

meet the electrical specifications

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

SP3491

is identical to

the

SP3490

with the addition of driver and receiver tri-state enable lines.
