SP481E / SP485E

Enhanced Low Power Half-Duplex

RS-485 Transceivers

Description

The

SP481E

and

SP485E

are a family of half-duplex transceivers that

meet the specifications of RS-485 and RS-422 serial protocols with

enhanced ESD performance. The ESD tolerance has been improved

on these devices to over ±15kV for both Human Body Model and

IEC61000-4-2 Air Discharge Method. These devices are pin-to-pin

compatible with MaxLinear’s SP481 and SP485 devices as well as

popular industry standards. As with the original versions, the SP481E

and SP485E feature Maxlinear’s BiCMOS design allowing low power

operation without sacrificing performance. The SP481E and SP485E

meet the requirements of the RS-485 and RS-422 protocols up

to 10Mbps under load. The SP481E is equipped with a low power

shutdown mode.
